Continuous wave, английский
- Continuous wave (cw) transmission is when there is an electromagnetic carrier wave present and the message signal, be it voice, video or data, is impressed upon the carrier by modulating its amplitude, phase or frequency. it is the system employed for terrestrial radio and tv transmissions. when the wave is unmodulated, the signal is highly monochromatic. the average power in the modulated wave is approximately that in the unmodulated carrier component.
- Wave of constant amplitude and frequency.
- Волна постоянной амплитуды и частоты.
