ANS 7

7. a) If a periodic signal is decomposed into five sine waves with frequencies of 200, 400, 600, 800 and 1000 Hz, show the bandwidth and illustrate the spectrum, assuming all components have a maximum amplitude of 10 V. b) Categorize the error detection method based on redundancy check. c) Assume, station A wants to send 111001 010100 111010 100111 bits to station Busing Longitudinal Redundancy Check (LRC) technique. Evaluate the transmission bits using LRC bits
