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 compares three basic digital modulation techniques—ASK, FSK, and PSK—by showing how a binary data stream is carried using a sinusoidal carrier. In ASK (Amplitude Shift Keying), the carrier amplitude changes with the data. When the bit is 1, the signal has higher amplitude; when the bit is 0, it drops or disappears. The main advantage is simplicity—easy to generate and demodulate. The drawback is noise sensitivity. Any noise that affects amplitude can easily cause bit errors, maki
