Electronic engineering

cathode terminal

Engineering; Electronic engineering

1. In a diode (semiconductor or tube), the terminal to which a negative dc voltage must be applied for forward-biasing the diode. Compare anode terminal. 2. In a diode, the terminal at which a ...

anode terminal

Engineering; Electronic engineering

1. In a diode, the terminal to which a positive dc voltage must be applied for forward bias. Compare cathode terminal. 2. In a diode, the terminal at which a negative dc voltage appears when the ...

1. In a direct-current (dc) generator, periodic reversal of the current in the armature coils as the coils alternately pass the north and south poles of the magnetic field. When the ends of each coil ...

commutator

Engineering; Electronic engineering

1. In a direct-current (dc) motor, generator, or rotating selector, an arrangement of parallel metal bars or strips on a rotating drum. As the drum turns, the bars contact one or more brushes that ...

center of beam

Engineering; Electronic engineering

1. In a directional antenna system, the direction, denoted by a straight ray, where the signal strength or response is the greatest. 2. In a beam of visible light, the geometric center of the spot ...

deviation

Engineering; Electronic engineering

1. In a frequency-modulated (FM) radio signal, the instantaneous amount of carrier frequency shift away from the unmodulated frequency. It is usually expressed in kilohertz; directly proportional to ...

band center

Engineering; Electronic engineering

1. In a given radio or television communications band, the arithmetic mean of the lowest and highest frequencies. 2. In a given band, the geometric mean of the longest and shortest wavelengths.
