A question about using fir1/fir2/firpm to design FIR filters in MATLAB. The first parameter is the 'filter order'. For my filter design I pass in 250 as this argument. However, when looking at the impulse response of the filter, it is a type 1 FIR filter. So my question is, is the filter order not the same as the number of taps? Is the number of taps one less, so 249 in this case, which gives the type 1 symmetry?
Cheers
