ABSTRACT:
A device for computing interpolated values of a waveform generated in an electronic device, includes a memory for storing waveform data of a periodic sinusoidal wave, and an address signal generator for generating an address signal. The waveform data consists of sine wave data and cosine wave data. An address signal from the generator or a signal obtained by inverting the address signal (i.e., inverted address signal) is supplied to the memory. Upon receipt of the address signal, the memory reads out the sine wave data or the cosine wave data. Upon receipt of the inverted address signal, it reads out the remaining wave data. The wave data read from the memory is multiplied by a multiplier, which produced an interpolated value. An adder adds this value to the sine or consine wave data read out from the memory when the inverted address signal is supplied to the memory, and computes amplitude value data corresponding to the address signal.
