frequency mixing
Also known as: wave mixing
Quick Summary
Frequency mixing, also known as intermodulation, is the production of new frequencies within an electrical device. These new frequencies are created by combining two or more input frequencies, resulting in output frequencies that are the sums and differences of the original frequencies, as well as their harmonics. This process is fundamental to the operation of devices like mixer tubes, which are electron tubes used for heterodyne operations. A mixer, in a broader sense, is any device or machine used for mixing.123
