11 years ago --- Quote Start --- I would like to know if it is possible to implement a 262144-tap FIR filter in a Stratix V? The input rate is 200kHz The input resolution is 18 bits The coefficient resolution is 18 bits. --- Quote End --- This is probably the wrong question. If you have such a huge number of taps, then you must have a very fast transition band, so the correct question is probably something like ... "how do I filter my wide bandwidth signal to narrow bandwidth? If you could describe what your filter is supposed to do in terms of input sample-rate and bandwidth, and output sample-rate and bandwidth, members of the forum can help point you in the right direction. Chances are you need a filter followed by decimation, in which case you can eliminate some of the calculations, and make an efficient filter. Have you read any books on filtering to determine your design? Cheers, Dave
