Abstract :
The computational cost for the design of FIR digital filters with short or medium length impulse responses is insignificant. However, the computational cost of conventional FIR filter design programs is 
, where 
denotes the length of the impulse response. Several hours of CPU time may be required to compute the coefficients in a very long filter, as for example in the case of 
. Here we discuss an improved method which can significantly reduce the computational requirements for the design of very long FIR digital filters.
