Continuous Wave (CW) Signals

Continuous Wave (CW) signals refer to a type of electromagnetic signal that is constant and uninterrupted over time. Unlike signals that vary in amplitude or frequency, CW signals maintain a steady frequency, making them ideal for applications like radar and communication systems. Think of it as a stable light beam that stays on without flickering. CW signals are often used in Morse code transmission, where the signal is turned on and off to send messages. Their simplicity makes them effective for reliable long-distance communication.
