|
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 |
