Filters
1. You need to design a lowpass filter with cutoff frequency Fc= 1MHz.
a. What is the minimum filter order required for 30 dB rejection (-30 dB gain) of 10 MHz?
b. What is the minimum filter order required for 30 dB rejection (-30 dB gain) of 2 MHz?
c. If you design a 4th order filter, what is your expected gain at 5 MHz?
2. You need to filter out 850 MHz to 950 MHz
a. What type of filter should you use?
b. If you design a 5th order filter, what is your expected gain at 85 MHz?
Mixers and Oscillators
1. A receiver uses a mixer to multiply a signal spanning from 900 MHz to 900.5
MHz by a reference tone
a. What frequency for a reference tone would be required to move the
signal down to baseband? (0 MHz to 0.5 MHz)
2. An oscillator produces a reference tone of 2.4 GHz. The accuracy of this
oscillator is 2 ppm.
a. What is the actual frequency range of the oscillator?
b. What kind of oscillator do you think this is? Why?
c. How many Hz would you expect this reference tone to drift over the
course of a second?
3. (3 bonus points) speculate as to why it might make sense to purchase an
atomic oscillator if a GPS oscillator is cheaper with similar performance.
