Communication Systems: Analog and Digital

Digital communication systems transmit information through discrete signals that represent binary data (0s and 1s). These signals are more resistant to interference and can be easily encrypted for secure transmission. Digital systems are widely used in applications such as:

Every modern digital communication system sits on top of an analog physical layer. Understanding Signal-to-Noise Ratio from Singh and Sapre is essential to understand Bit Error Rate in 5G. Understanding Nyquist Sampling is essential for digital oscilloscopes and SDRs. The analog concepts are the grammar of the language of communication.
