Programmable Pulse Generator using Simulink's basic blocks

The proposed Pulse Generator offers full tunability of its parameters on runtime.

Following steps explain the working principle of the proposed Programmable Pulse Generator:

1. Taking the modulus of the free running simulation "Clock" with the "Period", gives a triangular wave whose frequency is set by the "Period" input.

2. The multiplication of the "Period" with "PulseWidth"(in fraction instead of percentage), gives the On-Period of the Pulse.

3. Comparing the above generated triangular wave with this On-Period results into the Pulse waveform of desired frequency and pulse width. This is further scaled by the "Amplitude" input to achieve the desired peak magnitude.

4. The desired phase shift is achieved simply by:
a) subtracting the "PhaseDelay" input from the "Clock" and
b) using a switch to turn the "Amplitude" to zero till the "Clock" gets greater than the "PhaseDelay".
