This simulation shows the three major digital modulation techniques: Amplitude Shift Keying (ASK), Frequency Shift Keying (FSK), and Phase Shift Keying (PSK). In ASK (also known as On-Off Keying, OOK), the amplitude of the carrier is switched on and off depending on the binary input. It is simple to implement and widely used in low-cost applications like RFID tags, optical fiber communication, and remote controls. In FSK, the frequency of the carrier changes between two discrete values to repres

This simulation demonstrates the three fundamental digital modulation techniques by showing how a binary data signal alters a sinusoidal carrier. The top trace represents the digital input, switching between logic levels to encode data bits. In Amplitude Shift Keying, the carrier frequency remains constant while its amplitude changes with the data, making the signal easy to generate but more sensitive to noise. In Frequency Shift Keying, the carrier amplitude stays the same, but the frequency sw
