Dialog Box
FFT size
The size of the FFT, which should be a power-of-two value greater than the 
length of the specified FIR filter.
FIR coefficients
The filter numerator coefficients.
Output
The complexity of the output; 
Real or Complex. If the input signal or the 
filter coefficients are complex, this should be set to 
Complex.
