To generate varying phase shifted square wave, I am using pulse generator in Simulink. I want to make phase shift as a variable input to pulse generator. When I used variable time delay block, it changed the square wave output of pulse generator to triangular waveform. The method shown in figure is not working in the frequency range of 50 kHz.
Majid Moradi zirkohi I want to generate two square wave pulse phase shifted by certain phase in MATLAB/Simulink. I used the method as shown in figure attached but it is not working in the frequency range of 50 kHz. The output of variable time delay is becoming triangular pulse.
If a square wave becomes something similar to a triangular wave there are two possible reasons: you're implementing something which works similarly to a low pass filter or you're undersampling your simulation. Are you working with fixed or variable time step? Please provide some background about your simulation settings. You should be able to solve your problem by using a fixed sampling step at least 10x faster than your square wave.
