1. A radio channel consists of a bandwidth of 10 KHz and a SNR of 15 dB. Determine the maximum data rate which can be transmitted:
a) By using any system?
b) By using a code with 64 possible states?
2. A modulator transmits symbols, each of which consists of 64 different possible states, 15,000 times per second. Compute the baud rate and the bit rate?
3. Describe the Shannon limit for a standard telephone circuit with an SNR of 30 dB and a bandwidth of 3.3 KHz?
4. Describe the maximum data rate possible for a standard telephone circuit with an SNR of 1023 and BW of 3 KHz by using 8 bits per symbol?
