1. (TCO 1) In order to convert power into dB, we use 10log(X), but in order to convert voltage into dB we use 20log(x). Explain why.

2. (TCO 2) If SNR at the input of a system is 25 dB and SNR at the output of a system is 22 dB, what is the noise figure in dBs?

3. (TCO 2) Explain what is meant by a distorted signal. +

4. (TCO 3) If you are tuned to an AM station at 680 kHz, what are the frequency components of the AM signal?

5. (TCO 4) A 5-volt intelligence amplitude causes the frequency to change to ± 25 kHz, what will be the carrier frequency variation corresponding to an intelligence amplitude of 10 volts?

6. (TCO 4) What are the two functions of a limiter?

7. (TCO 5) How can we reduce quantization error in a PCM signal?
