i design 10th order analog low pass chebyshev filter & i want to plot its group delay versus frequency. i've already plotted using bode command , the phase & mag. response & i know that the group delay is the negative of the derivative of the phase of transfer function but how can i plot the...
thank you so much .. but i have another question now 'if u don't mind :$' when i plot the BER versus the OSNR for the chebyshev low pass filter of order =10 , when i use number of zero padding subcarriers=0 'since i'm using this filter in coherent optical OFDM system' and i found it don't...

thank you so much for your quick reply :) .. dunno , i feel that the first one is less complicated , so can you provide me with more details about it ? :)
I'm designing an analog chebyshev filter of order =10 and i want to know the formula of group delay , i know it's -1*derivative of phase of frequency response but i wonder if there is a clearer formula for the chebyshev filter relating the group delay with the filter order .. if you know i'd be...
