Electronics (Mike Jaroch)

A gas tube used as a modulator switching device [18].

A gas-filled triode in which a sufficiently large positive pulse applied to the
control grid ionizes the gas and causes the tube to conduct, after which the control grid has no effect in conduction [6] [12].

A small coil connected in series with the collector or plate circuit of a transistor or tube and inductively coupled to the base or grid-circuit coil to establish feedback (regeneration) [9].

Time required for an exponential quantity to change by an amount equal to 63.2 percent of the total change that can occur [2] [9].

The delay in a servosystem between the application of the input signal and the actual movement of the load [15].

The process that periodically samples the full 360 degrees of each sine wave. The sample can be of a received signal or of a signal to be transmitted [17].

See SYNCHRONIZER [18].

The process of applying a thin coat of solder to materials prior to their being soldered; for example, application of a light coat of solder to the filaments of a conductor to hold the filaments in place prior to soldering of the conductor [4].

(1) The maximum permissible error or variation from the standard in a measuring instrument. (2) A maximum electrical or mechanical variation of specifications that can be tolerated without impairing the operation of a device [1].

Equipment that converts TTY dc pulses into audio tones for modulation of a
transmitter in audio-frequency-tone shift transmissions [17].
