Homodyne is a technical term that is used to describe a type of radio frequency receiver. This word is often found in the field of electronics and telecommunications. Synonyms that can be used instead of homodyne include: synchronous detection, coherent detection, and direct conversion. These words refer to various techniques used to recover modulated signals from a carrier waveform. Synchronous detection refers to the extraction of a signal from a carrier by mixing it with a synchronizing signal. Coherent detection is a similar process where the carrier is mixed with a reference signal to recover the original signal. Finally, direct conversion is a technique that directly converts a modulated signal to a low-frequency signal for further processing.
