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 is how digital data (binary 1s and 0s) can be transmitted using different modulation techniques. A high-frequency carrier signal is modified based on the input digital signal using: Amplitude Shift Keying (ASK): Varies the amplitude—high for binary 1, low or zero for 0. Frequency Shift Keying (FSK): Switches between two frequencies—one for 1, another for 0. Phase Shift Keying (PSK): Changes the phase of the carrier signal to represent bits. #electronicsrd #ElectronicsEducation https://youtu
