The noise reduction circuit is based on the observation that noise is always disturbing in intervals when music stops. It will attenuate the signal output by about 45 dB, when the musical signal input ...

Noise reduction is an important process in any audio application circuits. One of the system used for audio noise reduction is the DNR or Dynamic Noise Reduction System, which is a single-ended or a ...

Separating the power/ground connections used for the analog sections from those used for the digital areas will improve the isolation of the power supplies. Adding external/internal filtering should ...

Digital transition switching is the primary cause of noise in mixed-signal devices. Signal noise and immunity to power, ground, and substrate noise all benefit from using differential circuits. Design ...
