Zusammenfassung:PROBLEM TO BE SOLVED: To provide an adaptive equalizer capable of minimizing the number of circuits to be added and improving a search capability. SOLUTION: This adaptive equalizer comprises a digital filter 6 and performs the adaptive equalization of digital signals. The digital IIR filter 6 comprises a number of filter blocks 8 and a search controller 14. Each of the filter blocks 8 serves as a circuit for digital filter processing while the search controller 14 serves as a circuit which determines the number of filter blocks 8 required for searching for a signal distortion part depending on variation in a digital signal transmission path.
