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
