Mechatronics Final Exam Review with
well researched solutions for study
Systematic Errors - CORRECT ANSWERS--Definite causes

-Reproducible

-Leads to inaccuracies



Random Errors - CORRECT ANSWERS--Non-Specific causes

-Not Reproducible

-Leads to Imprecision



Blunders - CORRECT ANSWERS-Engineer/scientist makes a mistake



Estimating Error - CORRECT ANSWERS--Nominal value: same number of sig figs as nominal value
measured



-Error: Same number of decimal places as nominal value



Ideal Voltage Source - CORRECT ANSWERS--Zero output resistance

-Supply infinite current



Ideal Current Source - CORRECT ANSWERS--Infinite output resistance

-Supply infinite voltage



Ideal Voltmeter - CORRECT ANSWERS--Infinite input resistance

-Draws no current

, Ideal Ammeter - CORRECT ANSWERS--Zero input resistance

- No voltage drop across it



Real Voltage Source - CORRECT ANSWERS--Small output impedence

-Minimizes voltage drop

-ideally Vs=Vout

-Needs to be considered for low impedence circuits



Real Current Source - CORRECT ANSWERS--Very large output impedence

-Minimizes current division effect

-ideally I_s=I_out

-Important when driving circuits with large impedence



Real Voltmeter - CORRECT ANSWERS--Very large input impedence

-Typically an order of 1 to 10 Mohms

-Must be considered when measuring voltage across a circuit branch with large impedence



Real Ammeter - CORRECT ANSWERS--Small input impedence

-Minimizing voltage drop added to circuit

-Important when measuring a circuit branch with small impedence



Oscilloscopes: AC Coupling - CORRECT ANSWERS--Used when intent is to block unwanted DC component
of a signal

-Low frequency signals are attenuated (acts as a high pass filter)

-Takes time for system to stabilize (about 5 time constants)
