Equipment that converts electromagnetic energy into an electrical signal that can be further processed.
Automatic Frequency Control
A circuit that keeps a receiver in tune with the wanted transmission.
The reception of so much power that component damage occurs.
The stage or circuit of a receiver where the audio or video signal is separated from the carrier signal. Normally a rectifier, the output of which drives a lower frequency device.
Noises produced within a receiver, consisting of four types:
- thermal agitation,
- shot effect
- hum from the a-c power source
Off Frequency Rejection
The amount of attenuation to a signal at a frequency other than the tuned frequency as a result of the selectivity characteristic of the receiver and the power-versus-frequency characteristic of the signal.
Receiver Noise Figure
A measure of signal-to-noise ratio degradation as the signal passes through the receiver.
