System Noise Floor and SNR Analyze the system shown in Figure NOIPS-33, assuming

The filter is lossless, and the antenna presents a signal whose power is −80 dBm to the input of the amplifier.

a. Find the total system input noise power. Answer in dBm.

b. Find the system output noise power. Answer in dBm.

c. What percentage of the input noise power is the antenna noise temperature responsible for?

d. What is the SNR of the signal presented by the antenna (i.e., including only antenna noise)? Answer in dB.

e. What is the SNR of the signal seen by the amplifier (i.e., including both antenna and amplifier noise)? Answer in dB.
