A fixed equalizer and a fixed equalization method compensates for amplitude distortion, delay distortion, etc., of a signal transmitted over a transmission line. A processor unit carries out filtering process, such as amplitude equalization, delay equalization, line equalization, etc., in accordance with parameters read from a memory. In view of the fact that amplitude equalization process can be achieved by a combination of a highpass filter and a lowpass filter and line equalization process can be achieved by a filter having an attenuating characteristic which is negative at low frequencies and positive at high frequencies, the present invention stores parameters providing a characteristic corresponding to the synthesis of the characteristics of such filters in the memory and performs filtering computation on the basis of the parameters.
