What does an oscilliscope display
electrical signals
How does X-Y mode on the oscilliscope work
Channel 1 plots x channel 2 plots y
How does a sine wave look in X-Y mode
Diagonal Line
How do 90 degree out of phase sines look on X-Y 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 non-inverting op amp
Non-inverting gives (1 + rf/rs) gain and inverting gives (-rf/rs) gain
What is the input current in an op-amp
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
