from this site, in the section titled 'group delay'

http://www.dspguru.com/info/terms/filtterm/index2.htm


i got an equation to calculate the 'group delay' of a linear FIR filter.

the equation is:

group delay = phase shift / -2pi


where phase shift is a value of radians / hz


can anyone please tell me how to calculate the phase shift with a basic FIR
filter in pd?
