Quadrature modulation: The signal behind digital communications

WebAmplitude modulation is one way of encoding a signal on a carrier wave. The carrier frequency remains constant but the amplitude of the carrier is modulated. To encode digital signals on the carrier, an agreement that full amplitude is the code for a 1 and zero amplitude is the code for a 0 is sufficient. WebThe amplitude of the PM and FM wave is constant. FM provides high-quality received signals while PM provides low-quality, received signals; The signal-to-noise ratio is better in FM compared to PM. Frequency Modulation and Amplitude Modulation: Comparison. In AM, modulation in amplitude occurs, while in FM, modulation in frequency occurs. In FM ...
