Pulse-width modulation — (PWM) of a signal or power source involves the modulation of its duty cycle, to either convey information over a communications channel or control the amount of power sent to a load. PrinciplePulse width modulation uses a square wave whose pulse… … Wikipedia
Pulse-Doppler radar — Pulse Doppler is a radar system capable of not only detecting target location (bearing, range, and altitude), but also measuring its radial velocity (range rate). It uses the Doppler effect to determine the relative velocity of objects; pulses of … Wikipedia
Pulse-code modulation — PCM redirects here. For other uses, see PCM (disambiguation). Pulse code modulation (PCM) is a method used to digitally represent sampled analog signals. It is the standard form for digital audio in computers and various Blu ray, Compact Disc and … Wikipedia
Pulse-amplitude modulation — Principle of PAM: (1) original signal, (2) PAM signal, (a) amplitude of signal, (b) time Pulse amplitude modulation, acronym PAM, is a form of signal modulation where the message information is encoded in the amplitude of a series of signal… … Wikipedia
Pulse-Width-Modulated (PWM) Wave Inverter — A type of power inverter that produce a high quality (nearly sinusoidal) voltage, at minimum current harmonics. *** (PWM) PWM inverters are the most expensive, but produce a high quality of output signal at minimum current harmonics. The… … Energy terms
Continuous-wave radar — is a type of radar system where a known stable frequency continuous wave radio energy is transmitted and then received from any reflecting objects.[1]Continuous wave (CW) radar uses Doppler, which renders the radar immune to interference from… … Wikipedia
APG-68 — The AN/APG 68 radar is a solid state long range (up to 300 km) Pulse doppler radar designed by Westinghouse (now Northrop Grumman) to replace AN/APG 66 radar in the F 16 Fighting Falcon. The AN/APG 68 radar system consists of the following line… … Wikipedia
History of radar — The history of radar starts with experiments by Heinrich Hertz in the late 19th century that showed that radio waves were reflected by metallic objects. This possibility was suggested in James Clerk Maxwell s seminal work on electromagnetism.… … Wikipedia
Radar signal characteristics — A Radar System uses a Radio Frequency electromagnetic signal reflected from a target to determine information about that target. In any radar system, the signal transmitted and received will exhibit many of the characteristics described below.The … Wikipedia
