Abstract
PURPOSE: To directly perform the operation of PCM by use of a digital memory which has recorded the operation results as to all the combinations of inputs.
CONSTITUTION: This each PCM signal P, Q is made an address input as to two PCM signal inputs P, Q, and a digital memory 30 which reads out its contents is provided. The digital memory 30 stores the operation results as to all the combinations of PCM signals P, Q of 8 bits to be input. The aforesaid operation results are read out by inputting the PCM signals P, Q as address. Accordingly, the operation output R can be directly received from the digital memory 30 to the output 20.
