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
