I am designing a filter in a receiver system.
What I need to know is : what is the relationship between the filter's group delay and system performance?
Filter's group delay can induce signal distortion, our receiver system has the design target of SNR, IIP3 and so on, but how these design targets can be related to filter's group delay?
I tried to use ADS to get the relationship, I put a cauer filter in the system, first I think I can find the distortion by substract the output signal of filter from the input signal of the filter, but because the delay between the input and output signal, they can not be direct substracted.
What can I do to analyze the relationship between filter's group delay and receiver performance?
Thank you very much.
