FIR Filters and required Coefficients

Question asked by ByronS on Jun 14, 2013

I'm trying to get an understanding of FIR filters and their benefits over other types of filters, since my knowledge of DSP fundamentals is still a work in progress. For example, I want to have a simple pass band of 200 Hz to about 6 KHz for part of my application with sharp edges to the response. I understand that a FIR filter provides very sharp edges, but beyond that I don't understand enough about DSP's to grasp what other benefit this filter type offers beyond some of the other filter types in SigmaStudio. After reading numerous posts, I understand I could overlap several General bi-quad filters to create a very steep roll-off at each edge of the passband. Wouldn't this achieve the same result or does it come down to the efficiency of resources required in SigmaStudio? My project is utilizing the 1701.

 

Any insight would be appreciated.
