from this site, in the section titled &#39;group delay&#39;<br><br><a href="http://www.dspguru.com/info/terms/filtterm/index2.htm">http://www.dspguru.com/info/terms/filtterm/index2.htm</a><br><br><br>i got an equation to calculate the &#39;group delay&#39; of a linear FIR filter.&nbsp; <br>
<br>the equation is:<br><br>group delay = phase shift / -2pi<br><br><br>where phase shift is a value of radians / hz<br><br><br>can anyone please tell me how to calculate the phase shift with a basic FIR filter in pd?<br>
