local oscillator
Receiver's internal signal
A local oscillator is an electronic component that generates a steady signal at a specific frequency, used in radio receivers and transmitters to convert incoming signals to a different frequency for processing.
The local oscillator signal mixes with the received signal to produce an intermediate frequency that's easier to amplify and filter.
Essential in superheterodyne receivers, radar systems, and telecommunications equipment.
