Digital-to-analog converter device
摘要:
A digital-to-analog converter device for PCM signals at different sampling frequencies (f s1 , f s2 . f s3 ) comprises a signal converter (6a) which expands the frequency distance between a PCM signal band and a side band by converting the sampling frequencies associated with the PCM signals to be reproduced into higher fequencies (2f s1 , 2f s2 ; f s3 ') ' With this signal converter, a single low-pass filter (4a) can be simplfied, having a gradual ramp cut-off characteristic for removal of the side band wherein a pass band cut-off frequency and a stop band cut-off frequency can be adapted for low pass filtering of the PCM signals at different sampling frequencies.
