Group delay equalizer

Hi every one. I want to calculate the group delay of my lowpass filter and then pre-distort my signal in order to compensate the group delay of lowpass filter. I know allpass filter is dealing with group delay, but I don`t know how to implement it is sysgen or hardware. Is there any reference to help me? Or any example to help me?

 

Best Regards

Arash

Re: Group delay equalizer

An all pass filter is an IIR filter so first you need to identify the coefficients of your IIR filter and then implement it in hardware which is not very hard. If you can write the matlab code for your design, it can be implemented in hardware.
