A digital signal processing apparatus and a digital signal recording apparatus using a digital signal mute method and a digital signal mute method and a digital signal processing apparatus using a digital signal processing apparatus and a digital signal recording apparatus using a digital signal mute method and a digital signal mute method.

摘要

The mute circuit for muting the 1-bit digital signal does not require any special circuit configuration. The mute signal for mating the 1-bit digital signal is selected so that the stop frequency of the endless response filter used to convert the 1-bit digital signal matches the spectral distribution of the mute signal generated corresponding to the mute command.
