The signal can be reconstituted by the pulse code demodulator. A difference amplifier is also supplied to allow the signal into the p.c.m modulator to be compared with the signal out of the. p.c.m demodulator in order to establish the loss of information(i.e. added noise) as a function of the encoding, frequency and amplitude
(a) To understand the working principle of delta modulation and demodulation. (b) Study of slope overload distortion and methods those are used for minimising it. Requirement: Trainer Kit ST2105 CRO. Introduction: Delta modulation is a system of digital modulation developed after pulse code modulation. In this system, at
The objective of this lab is to be familiarized with Pulse Code Modulation. Students are expected to write Matlab code, that will help them to understand the fundamentals of PCM. They will also observe the modulation and demodulation process of PCM using a pre-built hardware board. 2.2 Theory. Pulse Code Modulation

This experiment deals with the conversion of an analog signal into a digital signal, the coding of the digital signal into pulses (Pulse Code Modulation), and the recovery of the analog signal at the receiver end (demodulation). The integrated circuits that are utilized in this experiment are the Analog-to-Digital. Converter
