ASK, FSK, PSK Simulation: https://youtube.com/@electronicseducation?sub_confirmation=1 ASK (Amplitude Shift Keying): Modulates the amplitude of a carrier wave to represent digital data (e.g., high amplitude for '1', low for '0'). Used in optical fiber communication and RFID systems. FSK (Frequency Shift Keying): Represents digital data through discrete frequency changes of the carrier wave (e.g., f1 for '1', f0 for '0'). Commonly used in GSM, radio telemetry, and walkie-talkies. PSK (Phase Shift

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 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
