frequency mixing

Frequency mixing is a process used in electronics and communication where two different frequencies of signals are combined. When these signals mix, they produce new frequencies, called "intermediate frequencies," which are the sum and difference of the original frequencies. This technique is essential in devices like radios and televisions, allowing them to tune into specific channels and filter out unwanted signals. Essentially, frequency mixing enables efficient transmission and reception of information by transforming signals into a more manageable form for processing.
