Abstract
A signal mixing apparatus utilizing digital signal processing technology for mixing digital signals comprising parallel data of plural channels include an analog addition circuit for adding, in analog, data of the same bit of parallel input data in plural channels, an analog-to-digital conversion circuit for converting added analog data of respective bits to digital data, and a digital addition circuit for adding, in digital, the converted digital data of all bits together. Since the data of the same bit of parallel input data of plural channels are added together in analog through the analog addition circuit such as a bus and an analog adder, digital input data of a large number of channels can be mixed together with a small amount of wiring.
