This simulation demonstrates the three fundamental digital modulation techniques: ASK (Amplitude Shift Keying), FSK (Frequency Shift Keying), and PSK (Phase Shift Keying). The top waveform is the digital input signal, which controls the modulation. The green waveform shows ASK, where amplitude changes with the digital input. The orange waveform represents FSK, where frequency shifts based on logic levels. The red waveform shows PSK, where the phase of the carrier signal flips according to the in

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
