superheaterodyne
Definition
Noun: superheaterodyne is a type of radio receiver that uses a superheterodyne circuit, which mixes an incoming radio frequency signal with a locally generated signal to produce a fixed intermediate frequency (IF) for easier amplification and processing.
Usage Examples
- (A radio receiver that converts signals to an intermediate frequency.)
- (Historical radio receivers using this technology.)
- (The circuit enhanced the ability to isolate specific stations.)
Advanced Usage
- "superheaterodyne principle": the underlying concept of frequency mixing in radio reception.
- The superheaterodyne principle is fundamental to modern radio communications. (The technique of converting signals to a fixed intermediate frequency.)
Variants and Related Words
- Superheterodyne (adj/n): the standard spelling of the term; a receiver that uses frequency mixing.
- A superheterodyne radio is more sensitive than a simple crystal set. (A receiver with frequency conversion.)
- Heterodyne (adj): relating to the production of a beat frequency by mixing two signals.
- Heterodyne detection is used in radar systems. (Mixing signals to extract information.)
Synonyms
- Frequency converter: a device that changes the frequency of a signal.
- IF receiver: a receiver that processes signals at an intermediate frequency.
