Analog Electronics

26.

Which of the following?

Voltage series feedback and decrease I/P impedance.

Voltage shunt feedback and decrease I/P impedance.

Voltage series feedback and increase I/P impedance.

Voltage shunt feedback and increase I/P impedance.

Answer: Option

Explanation:

Because sample signal is voltage and feedback signal is also voltage. The drop in R_E change the input voltage at Base Emitter Junction.
