Figure 14.7 A series RC low- pass filter. Vj C: Vo Figure 14.7 Full Alternative Text
Design a passive RC low pass filter (14.7) with a cutoff
frequency of 100 Hz using a 4.7 μF capacitor.
1. a) What is the cutoff frequency in rad/s? 2. b) What is the value of the resistor?
3. c) Draw your circuit, labeling the component values and output
voltage.
4. d) What is the transfer function of the filter in part (c)?
5. e) If the filter in part (c) is loaded with a resistor whose value is the
same as the resistor part (b), what is the transfer function of this
loaded filter?
6. f) What is the cutoff frequency of the loaded filter from part (e)?
7. g) What is the gain in the pass band of the loaded filter from part
(e)?
