sampling - measurement at regular intervals of the amplitude of a varying waveform (in order to convert it to digital form)

electronic converter - (telecommunication) converter for converting a signal from one frequency to another

loop gain - (telecommunication) the gain of a feedback amplifier or system as a function of how much output is fed back to the input; "if the loop gain is too great the system may go into oscillation"

telecommunication - (often plural) the branch of electrical engineering concerned with the technology of electronic communication at a distance

medium - a means or instrumentality for storing or communicating information

telephony, telephone - transmitting speech at a distance

telegraphy - communicating at a distance by electric transmission over wire

wireless - transmission by radio waves

broadcasting - taking part in a radio or tv program

multiplex - communicates two or more signals over a common channel

plural, plural form - the form of a word that is used to denote more than one

sunrise industry - a new industry that is expanding rapidly (especially telecommunications or electronics)

sampling rate - (telecommunication) the frequency of sampling per unit time

Nyquist rate - (telecommunicaton) the lowest sampling rate that will permit accurate reconstruction of a sampled analog signal

sampling frequency - (telecommunication) the frequency of sampling a continuously varying signal

Nyquist frequency - (telecommunication) twice the maximum frequency occurring in the transmitted signal

call - send a message or attempt to reach someone by radio, phone, etc.; make a signal to in order to transmit a message; "Hawaii is calling!"; "A transmitter in Samoa was heard calling"
