Analog Electronics

Q1:
Which of the following?

A Voltage series feedback and decrease I/P impedance.

B Voltage shunt feedback and decrease I/P impedance.

C Voltage series feedback and increase I/P impedance.

D Voltage shunt feedback and increase I/P impedance.

ANS:C - Voltage series feedback and increase I/P impedance.

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