DIGITAL SIGNAL PROCESSING CIRCUIT

PURPOSE:To attain versatile processing function by providing a processing program required for the multi-functional signal processing and selecting a processing program in response to a processing function command. CONSTITUTION:A digital signal from an input terminal 1 is inputted to a digital signal processing operating section 6. On the other hand, the processing function and processing condition is transferred to a control section 5 via an interface section 4 from a command input terminal 3 as a command. The control section 5 decodes the command and controls the operating section 6 based thereupon. The operating section 6 selects the processing program in response to the command among prepared processing programs and executes the operation based on the selected processing program. Thus, the versatile processing function is attained in this way.
