PWM waveform pulse width & duty cycle info extraction

gte582

Hi, suppose I have a train of pulses in time domain, how can I extract

the  pulse width & duty cycle info?

Thanks,  

Parents

  • In IC615 there's a calculator function, dutyCycle which will allow you to plot the duty cycle versus time or cycle number. There's also a period_jitter function - which can do the period versus time or cycle number. If you wanted the pulse width, I guess you could do both versus cycle number and then multiply together (and divide by 100). Other than that for pulse width, you'd probably have to write something based on the cross() function using a bit of SKILL. Probably worth contacting customer support and asking for this as an enhancement though.

    Regards,

    Andrew.
