Voltage Series feedback also called series-shunt feedback) results in__________?
Correct answer: C. Increase in input impedance & decreases in output impedance
- A. Increase in both input & output impedances
- B. Decreases in both input & output impedances
- C. Increase in input impedance & decreases in output impedance
- D. Decrease in input impedance & increase in output impedance
Explanation
Voltage-series feedback mixes the feedback voltage in series at the input, increasing input impedance, and samples output voltage in shunt, decreasing output impedance. Therefore it increases input impedance and decreases output impedance.
