Introduction
A Comprehensive Guide to "Communication Systems: Analog and Digital" by Sanjay Sharma
In the evolving landscape of electronics and communication engineering, few subjects are as foundational as communication systems. For engineering students and aspirants preparing for competitive exams like GATE (Graduate Aptitude Test in Engineering) in India, one name stands out as a staple reference: Sanjay Sharma. communication systems analog and digital sanjay sharma pdf
- Basic idea: Vary carrier amplitude with message signal.
- Uses: AM radio, amplitude-shift keying (digital analog).
- Key points: Requires bandwidth equal to twice the message bandwidth; susceptible to amplitude noise.
6. Modern system examples (applied view)
- Cellular systems: OFDM, adaptive modulation, MIMO—blend analog RF frontends with heavy digital signal processing.
- Wi-Fi & Bluetooth: OFDM (Wi‑Fi) and FH/LE techniques (Bluetooth) tailored for local area connectivity.
- Satellite links: Emphasize high-power amplifiers (nonlinearities), long delay, and coding for reliability.
- Software-defined radio (SDR): Move flexibility to software—experiment with modulation, filtering, and protocols on commodity hardware.
