Abstract
A signal processor with a simplified circuit configuration provides an improved processing speed and can be realized of small size and at inexpensive cost. The signal processor includes signal holding means for holding output signals from plural signal sources (S1-S4), and signal mixing means (M31-M34) for mixing at least two signals among the plural signals held to output plural mixed signals. Since the mixed signals are less than the signal sources in number, the small number of signal lines can lead to an increased processing speed. Then the mixed signals corresponding to discrete signals from plural signal sources enables processing without substantially destroying information.
