Abstract
A signal-muting circuit, applied to a bridge amplifier comprises two amplifying means, performs signal-muting by shorting the input terminals of non-reversible buffer amplifiers forming the final stage of each amplifying means. Non-reversible amplifiers and said non-reversible buffer amplifiers in the amplifying means have the same voltage gain respectively.
Claims9
In a signal-muting circuit for a bridge amplifier having a potential source connected to two amplifying means each formed by connecting a non-reversible amplifier and a non-reversible buffer amplifier in series, an improvement characterized in that a switch is connected between the input terminals of the non-reversible buffer amplifiers as the final stage in each of said amplifying means so as to form a short-circuit whereby a signal is muted.
