what is the realistic channel capacity of a communication channel of 25KHZ that has 20db signal to noise ratio?

7) Suppose we have a message signal that is a sinusoid and we quantize it using a quantizer of L levels. Assuming that the quantization error for each sample is uniformly distributed in the interval , determine the signal to quantization noise ratio (SNR) in terms of L. Determine the SNR in terms of L if the message is changed to a triangular wave, again assuming that the errors are uniformly distributed.

To put it another way: A BTS broadcasting information with 10 W of output power at 1800 MHz can only cover half the area as a BTS transmitting at 900 MHz. Describe the benefits and drawbacks of using the 1800 MHz BTS to cover the same area as the 900 MHz BTS.

Consider a telephone line initially noiseless channel having bandwidth and signal level determined by the network engineer. Calculate maximum data rate. After certain distance the channel becomes extremely noisy, so that the noise is strong which faints the signal .Calculate the capacity of the channel.
