Modulation and Demodulation. Introduction. A communication system that sends information between two locations consists of a transmitter, channel, and receiver as illustrated in Figure 1. The channel refers to the physical medium carrying the information signal (voice, video, data etc.) from one location to another.
Showcasing the essential principles behind modern communication systems, this accessi- ble undergraduate textbook provides a solid introduction to the foundations of communi- cation theory.
Jul 27, 2015 · This note book gives a brief concepts about transmission line calculation and also provides an idea about communication system impairments with an example for each one.
The primary purpose of modulation in a communication system is to generate a modulated signal which is well suited to the characteristics of transmission medium. The audio frequency message signal carrying information can‘t be transmitted for distance directly without modulation.
Oct 31, 2023 · This paper presents an approach to evaluate communication technologies for industrial control systems during the system engineering phase, considering future application conditions.
A two-node, one-way communication system consists of the channel that conveys the waves, together with a modulator and a demodulator. All communications systems can be regarded as aggregates of these basic two-node units.
