<p>In a modulator/demodulator for modulating and demodulating a signal, transmission data and reception data are selected, data selected is set in an input register, Fourier- transform-processing or inverse-Fourier-transform processing is conducted on the data set in the input register, data of an N point (N is an arbitrary integer) processed is set in an output register, and an order to read out data of the N point set in the output register of Fourier transform means is specified, whereby transmission and reception processing for the signal can be carried out by a simple circuit arrangement having only one set of Fourier transform means. <IMAGE></p> |
