Electronic engineering

direct-conversion receiver

Engineering; Electronic engineering

A heterodyne receiver in which the incoming radio-frequency (RF) signal is amplified, then mixed with the RF output of a tunable local oscillator, producing an audio-frequency (AF) beat note. The AF ...

dynatron frequency meter

Engineering; Electronic engineering

A heterodyne-type frequency meter using a dynatron oscillator.

compressed-air capacitor

Engineering; Electronic engineering

A high voltage air-dielectric capacitor enclosed in a case in which the air pressure is held at several atmospheres. The device exploits the dielectric strength of compressed air, which is higher ...

directional diode

Engineering; Electronic engineering

A high-back-resistance semiconductor diode inserted into a direct-current (dc) signal circuit or control circuit. Permits unidirectional current flow.

Chireix-Mesny antenna

Engineering; Electronic engineering

A high-frequency (HF) beam antenna, in which each dipole section constitutes one side of a diamond. Cophased horizontal and vertical components of current flow in each of the diagonals, and radiation ...

carrier-type dc amplifier

Engineering; Electronic engineering

A high-frequency ac amplifier, ahead of which is operated a generator and transducer. A dc voltage applied to the transducer modulates the carrier supplied by the generator; the amplifier boosts the ...
