Because I need a raised cosine filter. If I convolve root raised cosine filter coefficients with themselves (generated with gr_firdes), do I need to apply a
scaling factor? From: Tom Rondeau [mailto:address@hidden

through a few sources, I have the following time-domain response of an RC filter: Sean, We've gotten this question before, and I'm again curious why you want a raised cosine filter? If you really are using it for something, the easiest thing to do is just create a root raised cosine filter and convolve it with itself. Tom |
