Signal means out of the ordinary or remarkable. An example of signal used as an adjective is the phrase a "signal win" which means a team that usually loses has just won.

signal: [adjective] distinguished from the ordinary: notable.

signal A signal is a gesture or message that people use to communicate with each other. The wave you give a good friend to call her over from across the room and the impulse that transmits your voice through the telephone to your mother are both signals. In the course of a single day, you probably send and receive thousands of different signals.

The th Signal Battalion (Special Operations) (Airborne) was established provisionally in June , with Bryan in command, and was formally activated at Fort Bragg on 17 September 12 It inherited the lineage of the World War II-era th Airborne Signal Company and the th Airborne Army Signal Battalion, both inactive since

The actual signal for the line is a varying wave between volts and volts, with volts representing black and 2 volts representing white. This signal drives the intensity circuit for the electron beam. In a black-and-white TV, this signal can consume about megahertz (MHz) of bandwidth, while in a color set the limit is about MHz.

Python installs a small number of signal handlers by default: SIGPIPE is ignored (so write errors on pipes and sockets can be reported as ordinary Python exceptions) and SIGINT is translated into a KeyboardInterrupt exception. All of these can be overridden. Some care must be taken if both signals and threads are used in the same program.

The analog signal must then be shifted in frequency and linearly amplified to the desired frequency and power level (linear amplification must be used to prevent modulation distortion). This low-level method for AM is used in many Amateur Radio transceivers.

Radio propagation is the behavior of radio waves as they travel, or are propagated, from one point to another, or into various parts of the atmosphere. As a form of electromagnetic radiation, like light waves, radio waves are affected by the phenomena of reflection, refraction, diffraction, absorption, polarization, and scattering. Understanding the effects of varying conditions on radio.

Apr 27,  · Typical sources of Wi-Fi signal impediments in residences include brick walls, large metal appliances, microwave ovens, and cordless phones. Sometimes, raising the height of the router improves the range because many obstructions are located at floor or waist height.
