What does a pulse generator do? A pulse generator is either an electronic circuit or a piece of electronic test equipment used to generate rectangular pulses. Pulse generators are used primarily for working with digital circuits, related function generators are used primarily for analog circuits.
As a consequence, What is the meaning of pulse generation?
n. A device that produces an electrical discharge at regular intervals, which can be modified as needed, as in an electronic pacemaker.
In this manner, How do you create a pulse in Matlab? y = pulstran( t , d , func ) generates a pulse train based on samples of a continuous function, func . y = pulstran( t , d , func , fs ) uses a sample rate of fs . y = pulstran( t , d , p ) generates a pulse train that is the sum of multiple delayed interpolations of the prototype pulse in vector p .
One may also ask, What is pulse train in Matlab?
The pulstran function generates pulse trains from either continuous or sampled prototype pulses. The pulse train is defined to have a sample rate of 50 kHz, a pulse train length of 10 ms, and a pulse repetition rate of 1 kHz. T specifies the time instants at which the pulse train is sampled.
Where are pulse generators placed?
A pulse generator is implanted subcutaneously into the left wall of the chest and is connected to bipolar electrodes, which are attached to the left vagus nerve within the neck.

What is pulse generator block diagram?
Square and Pulse Generator Block Diagram are used as measuring devices in combination with a CRO. They provide both quantitative and qualitative information of the system under test. They are made use of in transient response testing of amplifiers.
What is a pulse function?
The pulse button is used when you need short bursts of power at the optimum speed. This is controlled by the user which means you control how long the machine is run for. It is a useful way of avoiding over-processing.
How is pulse width measured?
Pulse Width (PW) is the elapsed time between the rising and falling edges of a single pulse. To make this measurement repeatable and accurate, we use the 50% power level as the reference points. The basic unit of measure for PRF is hertz (Hz). Use PRF to report the number of pulses per second.
What is duty cycle in MATLAB?
Duty cycle is the ratio between the duration of the pulse and the pulse period. For example, if a pulse duration is 1 microsecond and the pulse period is 4 microseconds, the duty cycle is 0.25. In a square wave, the time the signal is high is equal to the time the signal is low.
How do you square a pulse in Matlab?
Description. x = square( t ) generates a square wave with period 2π for the elements of the time array t . square is similar to the sine function but creates a square wave with values of –1 and 1. x = square( t , duty ) generates a square wave with specified duty cycle duty .
What is step function Matlab?
The step function is one of most useful functions in MATLAB for control design. Given a system representation, the response to a step input can be immediately plotted, without need to actually solve for the time response analytically.
How do you create a signal in Matlab?
What is an inductive pulse generator?
An inductive pulse generator for converting a rotary movement into a frequency proportional therewith. The pulse generator includes a measuring wheel (1) provided with poles (3) of magnetic material evenly distributed over the circumference of the measuring wheel.
What is a voltage pulse?
A pulse is a burst of current, voltage, or electromagnetic-field energy. Usually, the more positive voltage is called the high state and the more negative voltage is called the low state. The length of time between the rise and the decay of a single pulse is called the pulse duration or pulse width.
What is high voltage pulse generator?
Abstract: High voltage pulse generators can be used effectively in water treatment applications, as applying a pulsed electric field on the infected sample guarantees killing of harmful germs and bacteria. In this paper, a new high voltage pulse generator with closed loop control on its output voltage is proposed.
What is known as duty cycle?
Duty cycle is the ratio of time a load or circuit is ON compared to the time the load or circuit is OFF. Duty cycle, sometimes called "duty factor," is expressed as a percentage of ON time. A 60% duty cycle is a signal that is ON 60% of the time and OFF the other 40%.
What is an internal pulse generator?
The implantable pulse generator (IPG) is an electrical source that causes current to flow through the extension and lead wires to the electrode, across the electrode–tissue interface, and back through the tissue to the IPG case – the return electrode.
Why are pacemakers used?
Pacemakers are sometimes recommended for people with conditions that cause the heart to beat abnormally. Each time the heart beats, the heart muscle contracts (pulls inwards) in preparation for pumping blood around the body. The contractions are triggered by electrical pulses.
Is pulse rate heart rate?
The pulse rate is a measurement of the heart rate, or the number of times the heart beats per minute. As the heart pushes blood through the arteries, the arteries expand and contract with the flow of the blood. Taking a pulse not only measures the heart rate, but also can indicate the following: Heart rhythm.
What is superior node?
The SA node is the heart's natural pacemaker. The SA node consists of a cluster of cells that are situated in the upper part of the wall of the right atrium (the right upper chamber of the heart). The electrical impulses are generated there. The SA node is also called the sinus node.
What is the basic difference between square wave and pulse generator?
The key qualities that distinguish modern-day pulse generators from other types of square-wave-generating instruments are accuracy and resolution. Whereas AWGs have a limited frequency precision, consider the specs for a 100 MHz universal pulse generator from Berkeley Nucleonics Corp.
What is the use of sweep generator?
A sweep generator is a piece of electronic test equipment similar to, and sometimes included on, a function generator which creates an electrical waveform with a linearly varying frequency and a constant amplitude. Sweep generators are commonly used to test the frequency response of electronic filter circuits.
What is pulse and its types?
Types of pulses
The pulse felt on the neck is called the carotid pulse. When felt on the groin, it is called the femoral pulse. The pulse at your wrist is called the radial pulse. The pedal pulse is on the foot, and the brachial pulse is under the elbow. The normal apical pulse rate of an adult is 60 to 100 beats.
What is pulse and signal?
A pulse in signal processing is a rapid, transient change in the amplitude of a signal from a baseline value to a higher or lower value, followed by a rapid return to the baseline value.
What produces a pulse?
pulse, rhythmic dilation of an artery generated by the opening and closing of the aortic valve in the heart. A pulse can be felt by applying firm fingertip pressure to the skin at sites where the arteries travel near the skin's surface; it is more evident when surrounding muscles are relaxed.
What is the resolution of the pulse width?
Resolution of a PWM is the number of different steps you can have from zero power to full power. That is a 10 bit resolution means that you can have 1024 steps from zero to full power. Consider the example in which PWM is used to control the speed of a DC Motor.
How do you calculate PRF?
What is the difference between duty cycle and pulse width?
In electronics, duty cycle is the percentage of the ratio of pulse duration, or pulse width (PW) to the total period (T) of the waveform. Similarly, for pulse (10001000) the duty cycle will be 25% because the pulse remains high only for 1/4 of the period and remains low for 3/4 of the period.
How do you calculate duty cycle in Matlab?
Description. d = dutycycle( x ) returns the ratio of pulse width to pulse period for each positive-polarity pulse. The function identifies all regions that cross the upper-state boundary of the low state and the lower-state boundary of the high state.
