Abstract: An adaptive equalizer (100) has a signal converter (200) for performing a fast Fourier transform and/or an inverse fast Fourier transform. The signal converter (200) has: a first wide-bit memory (201) capable of reading/writing a plurality of sample signals; a first register group (202) comprising a plurality of registers capable of accessing the first wide-bit memory (201); a butterfly computation unit group (204) comprising a plurality of butterfly computation units; and a first connection switching unit (203) for switching the state of connection between the plurality of registers and the plurality of butterfly computation units.
