WebThe Types of Digital Modulation vs. Analog Modulation. Modulation refers to the technique of mixing two signals to transmit information. The two signals that are used in modulated communication are the carrier signal and the information signal. The only difference between analog and digital modulation is found in the information signals. Frequency modulation (FM) has numerous advantages over AM such as better fidelity and noise immunity. However, it is much more complex to both modulate and demodulate a carrier wave with FM, and AM predates it by several decades. There are several common types of FM demodulators: The quadrature … See more Demodulation is extracting the original information-bearing signal from a carrier wave.

WebJun 27, 2024 · Demodulation. When digital information is transmitted over an analog medium, such as a telephone line, an electronic waveform is modulated to contain the information. This analog signal is called a carrier wave. Demodulation is the act of extracting digital data from this signal once it reaches its destination. WebWhat is demodulation? The process of recovering the original information-carrying signal from a modified carrier wave is known as demodulation. A demodulator is a type of electrical circuit that is used to retrieve information from a modulated carrier wave.
