Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What is the formula for voltage gain (Av)?
- Vout/Vin
- Vin/Vout
- Vout + Vin
💡 Hint: Remember, gain measures how much the output is 'boosted' compared to the input.
Question 2
Is the ideal output impedance of a voltage amplifier zero?
- True
- False
💡 Hint: What impedance allows for no voltage drop?

Challenge Problems
Push your limits with challenges.
Question 1
A voltage amplifier receives 15 mV as input and produces 5 V as output. Calculate both the linear and decibel gains.
💡 Hint: Use the voltage gain formula followed by the dB conversion formula.
Question 2
Determine the bandwidth of an amplifier if the lower cutoff frequency is 100 Hz and the upper cutoff frequency is 20 kHz.
💡 Hint: Consider how to calculate the range by subtracting the lower from the upper frequency.
