Provided is a channel of 10 MHz bandwidth to be shared by 5 users. It is decided the channel is going to be shared by the users using FDM. A guard band of 1 MHz between each channel is allocated to avoid interference. Each user is given an equal share of bandwidth. Assume each user has 1 MB of data to transfer and can utilize the channel at full capacity. Calculate the time required to transfer all data when (i)...

*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).

3. The quality of a received signal is often characterized by the signal-to-noise-ratio (SNR), which is defined as SNR 10 log As you might expect from this Signal power in watts KTB definition, the unit of SNR is decibels (dB). The term in the denominator is the noise power, and it is generally specified as an effective noise temperature T multiplied by the product of Boltzmann's constant (K) and the bandwidth (B) of the signal in Hz. Generally we like...
