BGS Institute of Technology, Adichunchanagiri University (ACU)

The document contains questions from examinations in various subjects related to engineering. 1) The first part contains questions about wireless communication, embedded system design, biomedical signal processing, GSM, and data compression. The questions test concepts related to each topic including generations of cellular systems, mobile network operations, embedded system architecture, biomedical signals, GSM network architecture, and lossless vs lossy compression. 2) The second part continues with more advanced questions about wireless communication, GSM, telecom network management, error correction coding, electrocardiography, and portable medical monitoring. Concepts examined include interference reduction techniques, call setup, security protocols, network design factors, speech coding, QRS detection algorithms, and
