a. A communication network has a bandwidth of 10 kHz. Calculate the signal-to-noise ratio in dB if the capacity of the channel for a 100Kbps b. A communications channel with a bandwidth of 4kHz has a signal power to noise ratio of 7. Determine the Channel Capacity. c. The bandwidth in b above is reduced by 25%. How much should the signal power be increased to maintain the same channel capacity?
