Frequency Accuracy For the receiver shown as Figure 9-66:

a. What is the nominal tuned frequency of the receiver? In other words, to what frequency is the receiver tuned if both oscillators were perfectly accurate?

b. If all of the oscillators drift in the worst-case direction, what is the frequency of the signal leaving the 10.7 MHz filter? In other words, what is the farthest the output signal can deviate from 10.7 MHz? Give your answer in ppm.

c. For the worst-case condition, how much frequency offset (in Hz) is each oscillator causing?

d. Is the final output spectrum (at 10.7 MHz) inverted?
