  • $\begingroup$ (I'm sorry, I'm a total beginner and this was needed to be done as a part of a bigger project) While designing the filter, I definitely set the window sizes to be 5,10,13 and 15 and I don't know why its doing N/2 instead of N-1/2. Any inputs on how I can resolve this? edit: Is is possible that while specifying the window size in Matlab for this, it is automatically up-scaling the window size to +1 i.e. 5 to 6? hence giving 6-1/2=2.5 $\endgroup$ Commented Jul 22, 2020 at 11:53
  • $\begingroup$ @varungupta: You could add your code to the question. Then it's easier to know what's going on. $\endgroup$ Commented Jul 22, 2020 at 12:13

    $\begingroup$ @varungupta: It says "Filter order: 15", which means that the filter length = order+1=16, and the corresponding group delay is 15/2=7.5. 'Filter order' shouldn't be the same as 'window size', but window size = filter order + 1. $\endgroup$ Commented Jul 22, 2020 at 12:38
