Abstract
A digital signal composing circuit includes a first selector for selecting a plurality of digital data, a second selector for selecting one of the digital data and a feedback signal, a control circuit for controlling the switching of the first and second selectors and an adding circuit for adding outputs of the first and second selectors and supplying the added output to the second selector as the feedback signal wherein the final output is derived from the adding circuit. Thus, without using any multiplier, the signal processing can be widely used in the digital signal processing such as digital volume, cross-fade, fade-in/-out, mixing, linear interpolation and the like.
