Frequency response — is the measure of any system s spectrum response at the output to a signal of varying frequency (but constant amplitude) at its input. In the audible range it is usually referred to in connection with electronic amplifiers, microphones and… … Wikipedia
Frequency-hopping spread spectrum — (FHSS) is a method of transmitting radio signals by rapidly switching a carrier among many frequency channels, using a pseudorandom sequence known to both transmitter and receiver. A spread spectrum transmission offers three main advantages over… … Wikipedia
Frequency-division multiplexing — (FDM) is a form of signal multiplexing where multiple baseband signals are modulated on different frequency carrier waves and added together to create a composite signal. Non telephoneFDM can also be used to combine multiple signals before final… … Wikipedia

Frequency-division multiple access — or FDMA is an channel access method that is used by radio systems to share a certain radio spectrum between multiple users. The users are individually allocated one or several frequency bands, allowing them to access the radio system without… … Wikipedia
Frequency Scanning Interferometry — (FSI) is an absolute distance measurement technique, for measuring the distance between a pair of points, along a line of sight. The power of the FSI technique lies in its ability to make many such distance measurements, simultaneously. For each… … Wikipedia
System-on-a-chip — or system on chip (SoC or SOC) refers to integrating all components of a computer or other electronic system into a single integrated circuit (chip). It may contain digital, analog, mixed signal, and often radio frequency functions ndash; all on… … Wikipedia
