Question 1.
What is feedback in electronic systems?
Show hintHide hint
Think about regulatory mechanisms.
Question 2.
What happens to input resistance in an ideal feedback system?
Show hintHide hint
Focus on the effect of feedback on resistance.
3Question 3.
What does feedback mean in electronic circuits?
- Only increases output
- Only decreases output
- Can either increase or decrease the output
Show hintHide hint
Consider the types of feedback discussed.
4Question 4.
True or False: Higher feedback factor always leads to better circuit performance.
- True
- False
Show hintHide hint
Reflect on ideal versus non-ideal feedback discussions.
Question 5.
A system has a gain of 250 and a feedback factor of 0.04. What is the new output voltage if the input is 50 mV?
Show hintHide hint
Use feedback gain calculations as previously discussed.
Question 6.
If an amplifier with a feedback factor of 0.1 has an input resistance of 5 kΩ, how much does the input resistance change with feedback?
Show hintHide hint
Incorporate the desensitization factor for input resistance.
