What is meant by pulse train?

A pulse wave or pulse train is a type of non-sinusoidal waveform that includes square waves (duty cycle of 50%) and similarly periodic but asymmetrical waves (duty cycles other than 50%). It is a term used in synthesizer programming, and is a typical waveform available on many synthesizers.

What is the structure of the spectrum of a pulse train?

We see that the spectrum of the pulse train is a line spectrum centered at 1 GHz and a -4 dB bandwidth of 800 MHz. The distance between the lines is given by 1/ PRI and is 100 MHz. The pulse train and its spectrum represents the same signal. In stead of sending the pulse train one could send the line spectrum.

What is the use of pulse train?

Pulse train shaping allows the energy and/or width of each of a group of laser pulses to be delivered sequentially. This allows the energy input from the laser to be tailored to the specific application.

How do you define a pulse train 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 .
