Alexanderson

Engineering; Electronic engineering

American inventor who developed the first practical television system in 1930. He later improved upon his invention when he developed color television in 1955.

decibel (dB)

Engineering; Electronic engineering

A practical unit of relative gain. In terms of power, the relative gain in decibels is equal to: Gain (dB) = 10 log 10 ( P out /P in ), where P out is the output power and P in is the input ...

audio-frequency meter

Engineering; Electronic engineering

An instrument to measure frequencies in the audio-frequency spectrum (approximately 20 Hz to 20 kHz). Three types are commonly used: * Analog - Gives direct indications of frequency on the scale of a ...

Boltzmann's principle

Engineering; Electronic engineering

A description of the statistical distribution of large numbers of tiny particles under the influence of a force, such as an electric or magnetic field. When the system is in statistical equilibrium, ...

current-hogging injection logic (CHIL)

Engineering; Electronic engineering

A form of bipolar digital logic, similar to current hogging logic but having the greater density characteristic of injection logic.

current-limiting resistor

Engineering; Electronic engineering

A series resistor inserted into a circuit to limit the current to a prescribed value.

defeating

Engineering; Electronic engineering

1. The disabling or circumvention of an alarm or security system, leaving the protected property vulnerable to intrusion. 2. The dangerous, and potentially lethal, disabling of a safety device in an ...
