Electronic engineering

comeback

Engineering; Electronic engineering

A spurious response in a bandpass or band-rejection filter, at a frequency well above or below the passband or stopband.

dark-spot signal

Engineering; Electronic engineering

A spurious signal generated by some camera tubes, arising from secondaryemission effects.

audio squelch

Engineering; Electronic engineering

A squelch circuit that operates only on the audio channel of a receiver.

coherent reference

Engineering; Electronic engineering

A stable reference frequency with which other signals are phase locked for coherence.

carbon-film resistor

Engineering; Electronic engineering

A stable resistor whose resistance element is a film of carbon, vacuum-deposited on a substrate, such as a ceramic.

coaxial-tank oscillator

Engineering; Electronic engineering

A stable, self-excited oscillator that uses a coaxial tank. Also see concentric-line oscillator.

concentric-line oscillator

Engineering; Electronic engineering

A stable, self-excited oscillator whose frequency-determining tank consists principally of a section of concentric (coaxial) line. Used primarily at ultra-high frequencies (UHF).
