Abstract

PURPOSE:To obtain the multi-phase signal featuring the fixed phase difference by giving inversion to the triangular wave given from the triangular wave generator with addition of the DC voltage and then giving inversion again to the output with addition of the DC voltage to deliver selectively the triangular wave signals. CONSTITUTION:Receiving the triangular signal delivered from triangular wave generator 14, synchromous pulse generation circuit 15 generates the pulses at the time of rise and fall to then generate the clock pulse for counting of counter 16. While reverse circuit 18 gives inversion to the triangular wave given from circuit 14 and adds the DC voltage equivalent to the maximum value, and reverse circuit 19 gives inversion again to the output of circuit 18 with another addition of the DC voltage. After this, the waveform output of circuits 14, 18 and 19 each are supplied to data selectors 20-22, and the triangular wave signals are selected and delivered by the output signal of counter 16. In this way, the multi-phase signal featuring the fixed phase difference can be obtained.
