Glossary
Field-Effect Transistor
A circuit that generates precise frequency signals
by means of a single crystal oscillator in conjunc-
tion with frequency dividers and multipliers.
Frequency Modulation; the process of impressing
information on a radio signal by varying its fre-
quency.
Frequency Shift Keying; an FM technique for
shifting the frequency of the main carrier at a
Morse code rate. Used in the on-air identification
of frequencies.
The process of reducing the gain of a given ampli-
fier.
Undesirable energy at integral multiples of a
desired, fundamental frequency.
Frequencies in the 3.0 to 30.0 MHz range.
Frequencies affected by the pre-emphasis.
Input/Output
Light-Emitting Diode
The process by which a carrier is varied to repre-
sent an information-carrying signal.
Metal Oxide Semiconductor Field Effect Transistor;
a voltage-controlled device with high input imped-
ance due to its electrically isolated gate.
A transmission within a localized geographic area
(ranging from a single room to several kilometers).
Power Amplifier
Power Amplifier Current
Power Amplifier Voltage
A 19–kHz signal used for stereo transmissions.
