[PD] filter phase - group delay

2008-05-01 Thread hard off
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 pleas
