SUPERHET Meaning and
Definition
-
Superhet, short for superheterodyne, refers to a type of electronic receiver or radio that applies a process known as heterodyning to convert received radio frequency signals into a more manageable intermediate frequency. The term "superhet" originated from the combination of the words "super" and "heterodyne," highlighting the advanced features and principles behind this technology.
In a superhet system, an incoming radio frequency signal is mixed or combined with a generated local oscillator frequency. This mixing process creates a heterodyne or intermediate frequency that is easier to process and manipulate. The heterodyning action of the superhet allows for filtering, amplification, and demodulation stages to occur at a more stable frequency, simplifying the subsequent signal processing steps.
Superhet radios are known for their superior performance and ability to handle weak or noisy radio signals. They offer improved selectivity, sensitivity, and frequency stability compared to other types of receivers. The intermediate frequency stage in a superhet receiver allows for better filtering and subsequent processing, reducing interference and improving overall signal quality.
The superhet architecture is widely used in various radio applications, including AM (amplitude modulation), FM (frequency modulation), and more advanced digital modes. This technology has been highly influential in the development of modern communication systems and is still utilized in many radio equipment designs for its efficiency and performance benefits.
Common Misspellings for SUPERHET
Etymology of SUPERHET
The word "superhet" is an acronym for "superheterodyne", which comes from a combination of the Latin prefix "super" (meaning "above" or "beyond") and the Greek word "heteros" (meaning "different" or "other"). The term was coined in the early 20th century to describe a type of electronic circuit used in radio receivers.
The superheterodyne circuit was developed by Edwin Armstrong in 1918 as a way to enhance the sensitivity and selectivity of radio receivers. The circuit relies on the method of heterodyning, which involves combining two different radio frequencies to produce an intermediate frequency (IF). This intermediate frequency is easier to amplify and filter, improving the overall performance of the receiver.
The term "superhet" was commonly used to refer to radios or electronic devices that employed the superheterodyne circuit.
