Question 1.
What is a Bode plot?
Show hintHide hint
Think about how output relates to input over varying frequencies.
Question 2.
Define what a zero is in terms of Bode plots.
Show hintHide hint
Consider what happens to gain at specific points in a plot.
3Question 3.
What does a Bode plot illustrate about a CE amplifier?
- Input vs Output Voltage
- Voltage Gain vs Frequency
- Phase Shift vs Time
Show hintHide hint
Think about what you measure with a Bode plot.
4Question 4.
True or False: A zero in a Bode plot increases the overall gain.
- True
- False
Show hintHide hint
Recall how gain behaves at zeros.
Question 5.
A CE amplifier has a pole at 1 kHz and a zero at 10 Hz. Describe how the gain changes across these frequencies and sketch a rough Bode plot.
Show hintHide hint
Remember to identify the behavior before reaching the zero and after it, then relate how the pole reacts.
Question 6.
How would the design of a practical CE amplifier differ if a larger capacitor is used? Assess its influence on the gain.
Show hintHide hint
Consider the overall role of capacitance in determining circuit behavior.
