Title: Sine wave generating circuit
Inventor: SHIRATORI AKIHIRO
IPC: H03B28/00
Filed: 1993-02-05
Abstract: PURPOSE:To vary continuously a frequency of an output sine wave based on a clock input whose frequency is constant through the external setting of a frequency division ratio and coefficient data by providing a multiplier circuit multiplying frequency division data with the external coefficient data to the generating circuit. CONSTITUTION:A frequency division ratio M is set to a frequency divider circuit 4 by a binary value M and the circuit 4 applies 1/M frequency division to a clock CK to apply data CKM to a frequency divider circuit 5 once per MXT clock, where T is a period of the clock CK. Thus, output data A from the frequency divider circuit 5 at an optional time sampled by the clock period T are defined as a prescribed equation. An address NA given by low-order j-bits of the result of multiplication between the data A and a binary value N from an input terminal TN at a multiplier 1 is limited by 2<j>. Sine wave data Y being an output from an output terminal are expressed in a prescribed equation, and since a value N/M in the prescribed equation is set by an external input terminal, the output sine wave frequency is set optionally.
