beam-rider control system
Engineering; Electronic engineering
A missile-guidance system in which a control station sends a radio beam to a missile. The beam is moved in such a way that as the missile stays within the beam, it hits the target.
crystal mixer
Engineering; Electronic engineering
A mixer (converter) circuit utilizing the nonlinearity of a semiconductor diode to mix signals.
double local oscillator
Engineering; Electronic engineering
A mixer system in which a local oscillator generates two accurate radiofrequency (RF) signals separated by a few hundred hertz. The difference frequency is used as a reference in some applications.
Dolby B
Engineering; Electronic engineering
A modified form of Dolby A, with only one band of noise-reducing circuitry. It is used primarily by hobbyists.
color subcarrier
Engineering; Electronic engineering
A modulated monochrome signal whose sidebands convey color information.
crosshatch generator
Engineering; Electronic engineering
