What does an oscilliscope display

electrical signals

How does XY mode on the oscilliscope work

Channel 1 plots x channel 2 plots y

How does a sine wave look in XY mode

Diagonal Line

How do 90 degree out of phase sines look on XY mode oscilliscope

circle

How does Sweep mode work (triggering and slope)

Takes signal and chops it up, triggering value sets voltage to chop and slope decides wheter to chop when signal increasing or decreasing

What is a requirement for things to be measureed by oscilliscope

Need to be large enough

What are cursors on oscilliscope used for

Custom measurements

What do volts/division do

Each box is a division sets how many volts to fill

What are dmms used for measuring

Steady state

How do you read a resistor value

First, Second, Multiplier

What is a polarized capacitor

Have positive and negative terminal

How are capacitors measured

Farads

Ceramic Disck capacitor

Not polarized

How are breadboards connected

Vertical connected (sets of two) Horizontals connected across the gap but only in their own section

Ohms law

V=IR

Power

V^2 / R Watts

Power Max

I^2 * R

How does an ideal multimeter measure voltage

Infinite resistance

How does an ideal multimeter measure current

Zero Resistance

What kind of siganls can the generator make (3)

Sine, Square, Triangle

What can be controlled on the signal generator (3 thigns)

frequency amplitude offset

Capacitor Impedence

1 / jwc

frequency to radians per second

w = 2 * pi * f

Inductor impedence

jwl

difference between inverting and noninverting op amp

Noninverting gives (1 + rf/rs) gain and inverting gives (rf/rs) gain

What is the input current in an opamp

0

Voltage divider for Z2 with another Z1 (Vout / VIN)

= Z2 / (Z1 + Z2)

3DB means what

frequency at which we have half the power

Capacitor in DC

open circuit

Inductor in DC

short circuit

Low pass/ high pass

Low lets in low, High lets in high

Steps to solev analysis

1.) Write Impedence and Voltage divider equation
2.) Find voltage divider of circuit 3.) Find complex representation 4.) Find magnitude as M 5.) Find phase angle as A 6.) Plug into initial
