NF, MDS Given the system shown as Figure 5-91:

a. Find the noise figure at the center frequency of the RF BPF.

b. Find the noise figure at 1,100 MHz.

c. Find the minimum detectable signal (MDS) at the center frequency of the RF BPF.

d. How many poles do we need in the RF BPF to bring the signal at 1,100 MHz down to the system’s MDS? Use the MDS you calculated for the center frequency of the RF BPF. Let the noise bandwidth be 30 MHz
