Question 1
What happens to the gain of an amplifier when the frequency increases past the cutoff frequency?
- Gain increases
- Gain decreases
- Gain remains constant
💡 Hint: Think about how different frequencies affect circuit output.
Question 2
True or False: A Bode plot displays both gain and phase shift as functions of frequency.
- True
- False
💡 Hint: What dual characteristics does this plot convey?

Challenge Problems
Push your limits with challenges.
Question 1
You are designing a CE amplifier with a necessary cutoff frequency of 1 kHz. Given the relationship between R and C, determine suitable values for R if C = 10μF.
💡 Hint: Rearrange the formula to isolate R.
Question 2
A CS amplifier exhibits a phase shift of -90° at very low frequencies and approaches 0° at high frequencies. Analyze how this behavior impacts signal processing.
💡 Hint: Consider how shifts can combine or interfere with signals.
