![]() The verb tuning in radio contexts means adjusting the receiver to detect the desired radio signal carrier frequency that a particular radio station uses. Subcarriers are then processed like real radio transmissions, but the whole bandwidth is sampled with an analog-to-digital converter (A/D) at a rate faster than the Nyquist rate (that is, at least twice the IF frequency).Ī tuner can also refer to a radio receiver or standalone audio component that is part of an audio system such as a hi-fi or stereo, to be connected to a separate amplifier. RF input vswr and local oscillator level metering, conversion gain and image rejection, and noise figure. These are transmitted inside the receiver as an intermediate frequency (IF).
