Title:
PULSE DENSITY MODULATING DEVICE
Document Type and Number:
Japanese Patent JP3888565
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To perform pulse density modulation more accurately than a conventional manner in a pulse density modulating device.
SOLUTION: It is possible to establish linearity between corrected pulse density modulation waveform data SK and its DC component and to perform pulse density modulation even more accurately than a conventional way only by adding a waveform data correcting means by such a manner that the waveform data correcting means 40 that corrects the pulse density modulation waveform data SH is provided based on a clock correction signal S30 that shows the phase of an unequal cycle component included in a clock signal S7.
