data of 700 kbps is to be transmitted over a channel of 5 kHz bandwidth and 200 kbps capacity. The transmission should be free from the ISI problem. What should be the minimum value of the SNR (in dB unit) if the channel is noisy?

Please follow the steps for successive approximation technique to find a 8-bit encoding on a system with voltage ranging from 0V to 15V for the following two analog voltages (a) 5V and (b) 10V.

A PWM signal has a period of 100 millseconds. The initial pulse width is 10 millseconds. This means theresolution is 10%. True False

QUESTION 25 A microwave data link has been designed to operate at 110,000 symbols per second while encoding 14 bits per symbol. The receiving equipment requires at least a 50 dB signal to noise ratio in order to operate without significant error. At least 55 kHz of bandwidth on the transmission channel are required for the attempted system. The data rate of the designed link will be 1.54 Mbps. If the actual signal to noise ratio is 100 dB, the system could support encoding as many as 17 bits per symbol. There is not enough information given to determine the minimum transmission power needed to make sure an acceptable power level arrives at the receiver. Exactly 16,348 different symbols would be needed to support 17 bits per symbol. If the background noise at the receiver is -50 dBm, the receive power will need to be at least 1 dBm.
