 ## y = fftfilt (b, x) filters x with the FIR filter b using the FFT.
 ## y = fftfilt (b, x, N) uses the overlap-add method to filter x with
 ## b using an N-point FFT.

   ## If N is not specified explicitly, we do not use the overlap-add 
   ## method at all because loops are really slow.  Otherwise, we only
   ## ensure that the number of points in the FFT is the smallest power
