Digital Modulation Techniques (ASK, FSK, PSK, BPSK) - Amplitude, Frequency and Phase Shift Keying
Digital Modulation Techniques (ASK, FSK, PSK, BPSK) - Amplitude, Frequency and Phase Shift Keying

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
