Modem. A circuit or device that performs both modulation and Demodulation. See also Modem Specifications. A device used for converting digital, signals into, and recovering them from, quasi-analog signals suitable for transmission over analog communications channels.
Mode Shifting. In a magnetron, the inadvertent shifting from one mode to another during a pulse.
Mode Skipping. Operation in which the magnetron fires randomly, rather than firing on each
successive pulse as desired.
Modular Circuitry. A technique where printed circuit boards are stacked and connected together to form a module.
Modular Jack: A device that conforms to the Code of Federal Regulations, Title 47, part 68, which defines the size and configuration of all units that are permitted for connection to the public exchange facilities. Related; Telcom Connector Manufacturers.
Modular Packaging. Circuit assemblies or sub-assemblies packaged to be easily removed for
maintenance or repair.
Modulated Oscillator. An oscillator which has it's output modulated by another input signal.
Modulated Wave. A complex wave consisting of a carrier and a modulating wave that is
transmitted through space.
AM Modulated Wave
Modulating Wave. An information wave representing intelligence.
Modulation. The process of impressing one signal, containing intelligence, onto another signal which is used as a carrier. The process of impressing intelligence upon a transmission medium, such as radio waves. The three general types of modulation include Amplitude, Frequency and Pulse modulation. The process, or result of the process, of varying a characteristic of a carrier, in accordance with an information-bearing signal.
Modulation Circuit. A circuit that performs the function of modulation. Also refer to Transistor Amplitude Modulator Circuits.
Modulation Envelope. The wave shape that the signal outlines as a result of both the carrier wave and modulating signal in AM modulation. Also refer to Envelope Detector Circuits.
Modulation Factor. [M] An indication of relative magnitudes of the RF carrier and the modulating signal.
Modulation Index. The ratio of frequency deviation to the frequency of the modulating signal.
