Title: D/a converter
Inventor: OTSUKA JUN
IPC: H03M3/02
Filed: 1993-11-19
Abstract: PURPOSE:To improve pulse responsiveness in D/A conversion in a CD player, etc. CONSTITUTION:Data sampled with a sampling frequency fs is converted into the sampling frequency fs of (n) times by a digital filter Z, and is outputted via a selector 5. On the other hand, the output of the filter is thinned out to 1/n by a thinning circuit 4, and is set as fs data. A part where the data between samples is not changed is detected by a sample difference detection circuit 6, and such a pulse pattern is extracted by a discriminator circuit 17, and the output of the digital filter is set as data output in which an original filter is not applied in this section. However, when a discriminator circuit II8 detects the case that the input data of the digital filter is changed extending over three samples, the data of the digital filter are outputted before and after that. When a signal is of pulse waves, pulse wave output without ringing can be obtained, and a smooth reproduced waveform can be obtained in the case where either it is a general audio signal or constant data is continued in the audio signal.
