Pulse FFT analysis

Sub-system generates the pulses centered at defined angle with specified width at particular frequency.
Input of sub-systems are
1. Frequency
2. Center of the pulse
3. Half width (in terms of angles)

This model was developed to study the FFT of particular pulse sequence. Two subsystem used generates the waveform which may be the output of an inverter.
Provides a way to understand the FFT of the output wave of an inverter.
