*5. Suppose an analog signal has an absolute bandwidth of 10 KHz. It is sampled at the Nyquist rate and converted to a digital signal using an A/D converter such that the output signal-to-quantization noise ratio is at least 40 dB. Using your engineering judgment, choose the number of bits for the A/D converter and determine the bit rate (i.e., the number of bits/sec).

A video signal has bandwidth of 4 MHz. This signal is sampled, quantized, and binary encoded using the PCM technique. The video signal amplitude is uniformly distributed in the range (-2, 2). If the signal is sampled at the Nyquist rate and quantized into 512 levels: (a) Determine the bit rate. (b) Determine the signal-to-quantization-noise ratio. (©) If the signal-to-quantization-noise ratio must be increased by a factor of 16, how you can achieve that? Will this affect the bit rate?...
Data Communication and network
A metropolitan area is to be given wireless digital telephone service. Throughout this area there is approximately uniform service demand. Assume that the frequency is allocated in two blocks of 4 MHz with a separation of 50 MHz, one block for the uplink and the other for the downlink, which constitutes a frequency-division duplex (FDD) operation. The system uses the hybrid frequency-division/time-division multiple access (FD/TDMA) scheme as follows: The frequency band is divided into 500 kHz “channels” (which is the...

A metropolitan area is to be given wireless digital telephone service. Throughout this area there is approximately uniform service demand. Assume that the frequency is allocated in two blocks of \(4 \mathrm{MHz}\) with a separation of \(50 \mathrm{MHz}\), one block for the uplink and the other for the downlink, which constitutes a frequency-division duplex (FDD) operation.
