DIGITAL SIGNAL PROCESSING UNIT

摘要

PURPOSE:To obtain easily a prescribed characteristic by providing a memory storing a value corresponding to a setting value in a prescribed characteristic from a setting means. CONSTITUTION:Values corresponding to the setting values of setting variable resistors 141-148 in the prescribed characteristic are stored in optional addresses of a RAM18. Further, preset push buttons 1411-1418 are provided and an optional address of the RAM18 is selected by the pushbutton. Then a CPU13 reads the content of the selected RAM18 and sets the result to a buffer memory 19. Then the content of the memory 19 is fed to a digital signal processing unit 10 via a multiplexer 17 and a prescribed operation is conducted. The prescribed characteristic is obtained easily in this way.
