Title: Sine wave signal generating circuit
Inventor: ISHIGAKI TOSHIHIRO
IPC: H03B28/00
Filed: 1991-10-23
Abstract: PURPOSE:To provide the sine wave signal generating circuit which is small in circuit scale. CONSTITUTION:When a clock S11 rises, output signal S1-S24 of a hexadecimal counter 1 are set to +1 and the one-bit output signal S21 is outputted from the sine wave output signal S41 of the most significant bit of a sine wave output signal. In consideration of the fact that the values of the output signals S22-S24 of low-order three bits are equal in sine wave amplitude because of the symmetry of the waveform of a sine wave, a decoder 3 converts the values of the output signals S22-S24 of the low-order three bits into input signals S31-S33 of a sine wave table 2. The sine wave table 2 only has sine wave amplitude data at four points of 0-pi/2 among sine wave amplitude data obtained by dividing one period 2pi by 16, a value whose phase is (2pi/16)(counter value) is outputted with the output signals S21-824 of the hexadecimal counter 1, and sine wave output signals S41-S48 become a sine wave of one period with 16 clocks.
