2023 2024 MBA - VTU Notes for 6th SEM ECE

No worries I will get the Visvesvaraya Technological University notes of Unit 1 ECE Digital Communication Theory subject.

Chapter-1: Introduction
The purpose of a Communication System is to transport an information bearing signal from a source to a user destination via a communication channel.

The three basic elements of every communication systems are Transmitter, Receiver and Channel.

The Overall purpose of this system is to transfer information from one point (called Source) to another point, the user destination.

The message produced by a source, normally, is not electrical. Hence an input transducer is used for converting the message to a time varying electrical quantity called message signal. Similarly, at the destination point, another transducer converts the electrical waveform to the appropriate message.

Communication Systems are divided into 3 categories:
1. Analog Communication Systems are designed to transmit analog information using analog modulation methods.

2. Digital Communication Systems are designed for transmitting digital information using digital modulation schemes, and

3. Hybrid Systems that use digital modulation schemes for transmitting sampled and quantized values of an analog message signal.
