Final Exam review:

Question types:

What is an Operational Amplifier $($Op$-$Amp$)?$

Write some applications of an op$-$amp.

$2.$ What are the assumptions for an ideal op$-$amp?

$3.$ For an inverting amplifier, Proof that $\frac{Vo}{\text{V}\text{i}\text{n}}=-\frac{Rf}{R_1}$

$4.$ For non$-$inverting amplifier, Proof that $\frac{Vo}{\text{V}\text{i}\text{n}}=1+\frac{Rf}{R1}$

$5.$ For a summing amplifier circuit, proof that: $Vo=-(\frac{Rf}{Ra}{V}_a+\frac{Rf}{Rb}{V}_b+\frac{Rf}{Rc}{V}_c)$

$6.$ What is the alternating current $(AC)?$ What is the general format for sinusoidal voltage or current?

$7.$ What is phasor representation? How can a sinusoidal wave be represented as a phasor? Where can phasor algebra be applied?

$8.$ What is transfer function $H()?$ What are the $4$ types of transfer function?

$9.$ In what applications are $H()$ and $H(s)$ transfer functions commonly used?

$10.$ What are the $4$ stability conditions of a system?

$11.$ In mathematics how can we determine whether a circuit is stable or not?

All math$/$problems are important.
