71Satellite modem — A satellite modem or sat modem is a modem used to establish data transfers using a communications satellite as a relay.There is a wide range of satellite modems from cheap devices for home internet access to expensive multifunctional equipment… …
72Radiofrequency MASINT — is one of the six major disciplines generally accepted to make up the field of Measurement and Signature Intelligence (MASINT), with due regard that the MASINT subdisciplines may overlap, and MASINT, in turn, is complementary to more traditional… …
73Carrier-to-noise ratio — In telecommunications, the carrier to noise ratio, often written CNR or C/N , is the signal to noise ratio (SNR) of a modulated signal. The CNR is the quotient between the average received modulated carrier power C and the average received noise… …
74RF modulator — An RF modulator (for radio frequency modulator) is a device that takes a baseband input signal and outputs a radio frequency modulated signal.This is often a preliminary step in transmitting signals, either across open air via an antenna or… …
75Product detector — A product detector is a type of demodulator used for AM and SSB signals. Rather than converting the envelope of the signal into the decoded waveform like an envelope detector, the product detector takes the product of the modulated signal and a… …
76Atomic clock — Nuclear clock redirects here. For the clock as a measure for risk of catastrophic destruction, see Doomsday Clock. For a clock updated by radio signals (commonly but inaccurately called an atomic clock ), see Radio clock. For the album by Zion I …
77Retroreflector — Infobox Laboratory equipment name = Retroreflector caption = A gold corner cube retroreflector acronym = other names = uses = Distance measurement by optical delay line inventor = manufacturer = model = related = A retroreflector (sometimes… …
78Emergency population warning — An emergency population warning is a method whereby local, regional, or national authorities can contact members of the public en masse to warn them of an impending emergency. These warnings may be necessary for a number of reasons, including:*… …
79PICAXE — is the name of a UK sourced microcontroller system based on a range of Microchip PICs. There are 13 PICAXE variants of differing pin counts from 8 to 40 pins. Initially marketed for use in education and by electronics hobbyists, they are also… …
80Difference in the depth of modulation — The difference in the depth of modulation or DDM is used by instrument landing systems in conjunction with the associated airborne receiving equipment to define a position in airspace.[1] DDM is usually expressed in percentage but may also be… …
