Question 7

Receives high voltage signal

Answer 7

Power drive Amplifier

Question 8

Power Drive Amplifier acts to:

Answer 8

increase power of signal so that it can drive another instrument/device

Question 9

Rule 1 of Op Amps

Answer 9

when the op amp is in the linear range, the two input terminals are at the same voltage

Question 10

Rule 2 of Op Amps

Answer 10

No current flows into either input terminal of the op-amp

Question 11

Equation for inverting amplifier

Answer 11

V0/Vi = -Rf/Ri

Question 12

Equation for follower

Answer 12

V0/Vi = 1

Question 13

Purpose of Follower:

Answer 13

Acts as buffer and decrease system impedance

Question 14

Equation for non-inverting amplifier

Answer 14

V0/Vi = 1 + (Rf/Ri)
