Learning

Practice Questions

Test your understanding with targeted questions related to the topic.

Question 1

Easy

What is the output voltage when the input is 100 mV and the gain is 10?

πŸ’‘ Hint: Apply the formula: Output Voltage = Gain x Input Voltage.

Question 2

Easy

Define the term 'voltage gain'.

πŸ’‘ Hint: Think about how much the input signal is amplified.

Question 1

What is the effect of negative feedback on the voltage gain?

  • It increases voltage gain
  • It has no effect
  • It decreases voltage gain

πŸ’‘ Hint: Think about how feedback helps control outputs.

Question 2

True or False: An ideal feedback system has infinite input resistance.

  • True
  • False

πŸ’‘ Hint: Consider the ideal characteristics described in class.

Challenge Problems

Push your limits with challenges.

Question 1

In a feedback system with A = 250 and Ξ² = 0.05, calculate the new voltage gain if the input signal is 200 mV and derive the final output voltage.

πŸ’‘ Hint: Make sure to start from calculating the voltage gain first!

Question 2

Discuss how altering Ξ² from 0.05 to 0.1 impacts the new output voltage and input/output resistances. Assume A remains constant.

πŸ’‘ Hint: Reference how we calculated resistances related to feedback factors.
