How an AC amplifier can be powered by a single supply voltage, produces voltage swing?
A. By inserting a voltage divider at the inverting input
B. By inserting a voltage divider at the non-inverting input
C. By inserting a voltage divider at the output
D. By inserting a voltage divider at the feedback circuit
Answer:A

A. By inserting a voltage divider at the inverting input B. By inserting a voltage divider at the non-inverting input C. By inserting a voltage divider at the output D. By inserting a voltage divider at the feedback circuit
Explanation: A positive dc level is intentionally inserted using a voltage-divider network at the non-inverting input terminal, so that output can swing both positively as well as negatively. 2. Given below are the circuits connected to the non-inverting input terminal of AC amplifier. Choose the circuit which produces positive output swing equal the negative?
