Abstract
A variable signal attenuating circuit which has a function of preventing dropout of an attenuated signal even if a large attenuation value is set. A dynamic range compression processing unit is provided in an input unit of the variable signal attenuating circuit for compressing the dynamic range of an input signal within a predetermined range in accordance with a set attenuation value, such that the signal passing through the compression processing unit is attenuated by the set attenuation value.
Claims5
A variable signal attenuating circuit for use in audio equipment, comprising:
- attenuation value setting part for setting a predetermined attenuation value;
- dynamic range compression processing part for compressing a dynamic range of an input signal within a predetermined range;
- and
- signal attenuating part for attenuating the input signal which has passed through said dynamic range compression processing part based on said attenuation value,
- wherein said dynamic range compression processing part determines a compressed range based on said attenuation value when compressing the dynamic range of the input signal within the predetermined range.
