Hey guys, Im fairly new at DSP and pure data in general. At the moment i am trying to learn how to show the Frequency response and Impulse response of my Comb filter in pD. I have been trying with tabwrite~ object but I'm not sure I'm getting the right result. I have searched for this problem around and maybe I am just not knowledgeable enough to actually spot the correct solution, so I would really appreciate it if someone steers me in the right direction.

tabwrite~ will work for the impulse response. after that, you have to do a windowed fft on the resulting impulse response in order to get the frequencies present. sorry I don't have a more detailed explanation.
of course, in order to get an impulse response you need to feed your filter a 1 sample impulse and record it to tabwrite~ at the same time

Alright, I suppose it wasnt as simple as i thought it would be. Thanks for the reply, i'll look into it.

You can have a look to these patches Fltr.
