1. ideal equalizer of utilizing infinite impulse response filter is characterized in that it comprises:

  • N infinite impulse response filter is in order to receive an input signal;

    N gain adjustment is respectively coupled to those infinite impulse response filters, in order to produceN gain adjustment output;

    AndOne adder, in order to those gain adjustment outputs of totalling, producing a desirable output signal such as gradeization,Wherein, N is the positive integer greater than 2;

    The frequency transform function of said infinite impulse response filter is respectively SB 1(f)~

    SB N(f), it meets following relation;
