ABSTRACT:
A signal processing apparatus includes a switching unit for switching one input signal to be processed and outputting the switched signal. Signal processing units have the same structure, and each of the signal processing units comprises a plurality of signal processors for subjecting an input signal to be processed to predetermined signal processing. Each signal processor has an inherent signal processing error. A control unit controls a switching operation of the switching unit so that the switched signal output from the switching unit is input to an arbitrary combination of the signal processors. A synthesizing unit synthesizes outputs from the arbitrary combination of signal processors and produces one output signal in which the inherent signal processing error of each signal processor has been averaged.
