... desired response signal d(n) consists of a sum of a broadband signal and a nearly periodic signal, and it is desired to separate these two signals without specific knowledge about the signals (such ... input signal x(n) is derived from the desired response signal as x(n) = d(n − ) , (18.13) where  is an integer value of delay. In effect, the input signal serves as the desired resp...
