Circuitry for sequentially producing the function values of several oscillations whose follow frequencies amount to N times a fundamental frequency

摘要

Circuitry for sequentially producing the function values (W) of several oscillations, the subsequent frequencies of which amount to N-times a fundamental frequency (SCH1). A counter (Z) periodically outputs p counts (A) in binary representation. A generator (NG) generates binary signals (N) which signal the numbers (N). A multiplier (MU) multiplies the counts (A) in modulo p by the numbers N and the resultant multiplicative signals (AN) are used for addressing a read-only memory (ROM) which outputs the corresponding function values (W).
