ABSTRACT:
An apparatus for testing the operation of a digital signal processor in an optical disk player includes a microcomputer for generating a control signal representative of a data transmission speed of the optical disk player. The microcomputer also evaluates the operation of the digital signal processor based on a digital signal received from the digital signal processor. A pattern generating unit receives the control signal, generates a radio frequency signal corresponding to the data transmission speed in response to the control signal, and provides the radio frequency signal to the digital signal processor. The digital signal processor generates the digital signal in response to the radio frequency signal. A display provides display of the result of the evaluation performed by the microcomputer.
