When a digital signal undergoes Pulse Code Modulation, it converts the analog information into a binary sequence (1 and 0). Through the demodulation process, we can obtain the original analog signal. The figure below represents the output of the PCM signal with respect to the sine wave.
A PCM system converts an analog input signal to the digital signal, which is a combination of the binary sequence created from the binary digits 0 and 1. An analog signal is a continuous wave, and the PCM signal is a wave with a series of digits.
Apr 15, 2016 · Pulse-code modulation or PCM is known as a digital pulse modulation technique . In fact, the pulse-code modulation is quite complex as compared to the analog pulse modulation techniques i.e. PAM, PWM and PPM, in the sense that the message signal is subjected to a great number of operations .
May 10, 2018 · This type of digital pulse modulation technique is called as Differential Code Modulation (DPCM). Working Principle. The differential pulse code modulation works on the principle of prediction. The value of the present sample is predicted from the past samples. The prediction may not be exact but it is very close to the actual sample value.
Aug 31, 2023 · Learn the difference between Pulse Code Modulation (PCM) and Delta Modulation (DM), two methods of converting analog signals to digital signals. Compare their features, advantages, disadvantages, and applications with examples and diagrams.
