Abstract

PURPOSE: To exclude the sampling means and the A/D converter and simplify the circuit constitution, by sampling the analog signals and storing the sampling values successively into a memory element.
CONSTITUTION: Both the gate and the substrate of the floating memory element M are connected to the ground level G of sound signal. The source is opened, and the drain is connected to the output terminal of the differential amplifier OA. The aural signal is converted by the amplifier OA so that the level of each sampling point is within the writing voltage range of the element M, and then applied to the drain of the element M. To store all sampling values as the aural signals, the memory elements are set in parallel and each sampling value is stored in each memory element with a correspondence secured respectively.
