  1. Continuous wave - Wikipedia

    https://en.wikipedia.org/wiki/Continuous_wave

    A continuous wave or continuous waveform (CW) is an electromagnetic wave of constant amplitude and frequency, typically a sine wave, that for mathematical analysis is considered to be of infinite duration. Continuous wave is also the name given to an early method of radio transmission, in which a sinusoidal carrier wave is switched on and off. Information is carried …

  2. Continuous-wave radar - Wikipedia

    https://en.wikipedia.org/wiki/Continuous-wave_radar

    Continuous-wave radar (CW 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. Individual objects can be detected using the Doppler effect, which causes the received signal to have a different frequency from the transmitted signal, allowing it to be detected by filtering out …

  3. CW – Wikipedia, wolna encyklopedia

    https://pl.wikipedia.org/wiki/CW

    CW (ang. continuous wave lub continuous waveform) – rodzaj emisji fali elektromagnetycznej (radiowej) ze stałą amplitudą i częstotliwością – na przykład fala ciągła z kluczowaną nośną A1A.Fala nadawana tą emisją jest emitowana z przerwami, a długości czasu nadawania i przerw kodują przenoszoną informację. Obecnie używana głównie przez krótkofalowców do transmisji ...
