- 2to mix two signals together in a way that produces audible sound
- 3a method of producing a new frequency by mixing two different frequencies
Using heterodyne: Examples
Take a moment to familiarize yourself with how "heterodyne" can be used in various situations through the following examples!
Example
The radio receiver heterodynes the incoming signal with a local oscillator to produce an intermediate frequency.
Example
The guitar pedal heterodynes the input signal with an internal oscillator to produce a distorted sound.
Example
The radar system heterodynes the transmitted signal with the received signal to produce a Doppler shift.
heterodyne Synonyms and Antonyms
Phrases with heterodyne
heterodyne detection
a technique used to detect weak signals in the presence of noise
Example
The heterodyne detection method is commonly used in radio astronomy.
the difference between two frequencies that are mixed together to produce a new frequency
Example
The heterodyne frequency is equal to the difference between the local oscillator frequency and the incoming signal frequency.
a type of radio receiver that uses heterodyne mixing to convert high-frequency signals to a lower, more easily processed intermediate frequency
Example
The heterodyne receiver is widely used in modern radio communication systems.
Origins of heterodyne
from Greek 'heteros' meaning 'different' and 'dunē' meaning 'tone'
