Continuous Wave

A Continuous Wave (CW) is a steady, unmodulated signal that remains constant over time, typically used in radio and communications. Unlike pulsed signals that turn on and off quickly, CW continuously transmits radio energy at a fixed power and frequency. This steady transmission allows for precise detection and measurement, because the receiver can focus on a specific, uninterrupted signal. CW is commonly used in Morse code communications and radar systems, enabling efficient and reliable transmission of information by maintaining a continuous, unchanging wave.
