A filter counting number generator of a HDTV equalizer provides an initial filter counting number used in a blind equalizer, and does not need a training signal. The counting number generator includes: a filter counting number renewing part(102) for generating a renewed filter counting number(BW1(K), BWq(K), and an input signal; an initial filter counting number generator(104) for generating an initial filter counting number(IWi, IWq) for a predetermined period; a selection signal generator(106) for generating a selection signal(S); and a first selecting part(108) which receives the output signals of the renewing part(102) and the counting number generator(104), and corresponds to the selection signal(S) provided from the selection signal generator(106).
