DIGITAL SIGNAL MIXING APPARATUS

摘要

In a digital signal mixing apparatus for mixing S-channel input digital signals to obtain T-channel output digital signals, there are provided a memory in which matrix elements ¢S x T! are stored with digital form, a circuit which determines the matrix elements ¢S x T! in response to a desired mixing ratio between the S-channel input digital signals and supplies the above matrix elements to the memory, and a circuit which operates the S-channel input digital signals with the matrix elements read out from the memory to generate the T-channel output digital signal therefrom.
