1Standard time and frequency signal service — The Standard Time and Frequency Signal (STFS) is a service available in the United States (centered at 10.000MHz? .jg) which provides standard time and frequency signals, broadcast on very precise carrier frequencies by the U.S. Naval Observatory …
2Transmitter — For biologic transmitters, see transmitter substance. Commercial FM broadcasting transmitter at radio station WDET FM, Wayne State University, Detroit, USA. It broadcasts at 101.9 MHz with a radiated power of 48 kW. In electronics and… …
3Frequency-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… …
4Transmitter hunting — (also known as T hunting, Fox Hunting, Bunny Hunting, and Bunny Chasing, is an activity wherein participants use radio direction finding techniques to locate one or more radio transmitters hidden within a designated search area. This activity is… …
5Signal integrity — or SI is a measure of the quality of an electrical signal. In digital electronics, a stream of binary values is represented by a voltage (or current) waveform. Over short distances and at low bit rates, a simple conductor can transmit this with… …
6Signal reflection — occurs when a signal is transmitted along a transmission medium, such as a copper cable or an optical fiber, some of the signal power may be reflected back to its origin rather than being carried all the way along the cable to the far end. This… …
7Frequency mixer — This article is about non linear mixing operating in the frequency domain. For other types of mixers, see electronic mixer. Frequency Mixer Symbol. In electronics a mixer or frequency mixer is a nonlinear electrical circuit that creates new… …
