1. Data is to be transmitted using a modem at 9600 bps. Determine the minimum bandwidth of the system with the following modulation methods
(a) FSK
(b) ASK.
Use the excess bandwidth factor r = 0:5. Compare ASK and BFSK in terms of transmission bandwidth for a constant data rate.
Design and simulate by using multisim software a series voltage regulator to supply 1A to a load at a constant voltage of 9V. The supply voltage to regulator is 15V±10%. The minimu
how does the increase in the kinetic energy of a proton compare with the increase in kinetic energy of the alpha particle in part?
Problem: (a) Compare the different MAC schemes, namely FDMA, SDMA, TDMA and CDMA. (b) Describe with help of diagrams the different phenomena involved in multipath propaga
Demand Meters Demand meters measure volt-amperes (in kVA), that merge both reactive (reflected) and actual (consumed) power. In its easiest form, a demand meter has a gauge wh
