发明名称
摘要 A digital signal mixing apparatus for mixing digital signals in S input channels to obtain digital mixed signals in T output channels is provided which includes a memory in which a matrix of S columns by T rows of elements are stored in digital form, a circuit which determines the value of the elements of the S by T matrix in response to a desired mixing ratio between the S-channels of the digital input signals and supplies these matrix elements to the memory, and a circuit which multiplies the digital signals in the S input channels by corresponding matrix elements read out from the memory to generate the digital mixed signals in the T output channels.
