group delay equations - RF Cafe Forums

The original RF Cafe Forums were shut down in late 2012 due to maintenance issues - primarily having to spend time purging garbage posts from the board. At some point I might start the RF Cafe Forums again if the phpBB software gets better at filtering spam.

Below are the old forum threads, including responses to the original posts.

Hi. Who knows where I can have group delay equations for filters Butterworth, Chebyshev and others?

I need closed form solutions not differential where I must do GD from delta phase on point by point basis. Thank you for your help to me.
