![]() ![]() ![]() The basic difference between continuous wave Modulation and digital modulation techniques is based on the nature of message signal (modulating signal). So now let's understand the basic difference between continuous wave modulation and digital modulation-ĭifference between Continuous Wave Modulation and Digital Modulation:Īmplitude Modulation (AM), Frequency Modulation (FM) and Phase Modulation (PM) are the examples of Continuous Wave (CW) modulation, while Amplitude Shift Keying (ASK), Frequency Shift Keying (FSK) and Phase Shift Keying (PSK) are examples of Digital Modulation Techniques. HDMI Encoder Modulator, 16in1 Digital Headend, HD RF Modulator at So if amplitude of the carrier wave is varied, then it is called as amplitude modulation, but if frequency or phase of the carrier wave is varied, according to the instantaneous value of the modulating signal, then it is known as frequency modulation or phase modulation respectively. Phase) is varied in accordance with the instantaneous value of the modulating (message or baseband) signal. ![]()
