Encoding
This document provides an in-depth overview of various digital and analog encoding schemes used in telecommunications. It covers critical concepts such as digital-to-digital encoding, including unipolar, polar, and bipolar encoding methods, along with the principles of pulse amplitude modulation (PAM) and pulse code modulation (PCM). Additionally, it discusses digital-to-analog encoding, including amplitude shift keying (ASK), frequency shift keying (FSK), and phase shift keying (PSK). Readers will also explore the Nyquist theorem and the distinctions between bit rate and baud rate, making this guide essential for telecommunications professionals.
