Method of muting a digital signal and a digital signal recording apparatus and a digital signal processing apparatus employing the digital signal muting method

摘要

A muting circuit for muting a 1-bit digital signal which is not in need of a special circuit configuration, which a muting signal for muting the 1-bit digital signal is selected such that the inhibiting frequencies of an infinite response filter used for converting the 1-bit digital signal will be coincident with the spectrum distribution of the muting signal generated responsive to a muting command.
