Consider the low-pass filter , which has a load resistor RL.
1. a) What is the transfer function of the unloaded filter? 2. b) What is the transfer function of the loaded filter?
3. c) Compare the transfer function of the unloaded filter in part (a)
and the transfer function of the loaded filter in part (b). Are the
cutoff frequencies different? Are the passband gains different?
4. d) If R=330 Ω and L=10 mH, what is the cutoff frequency of the
unloaded filter in rad/s?
5. e) What is the smallest value of load resistance that can be used
with the filter components in part (d) so that the cutoff frequency of
the resulting filter is no more than 5% different from the unloaded
filter?
