MAE 2381 EXAM 1 QUESTIONS AND
ANSWERS 100% VERIFIED
resolution - ANSWERsmallest increment in the measured value that can be
discerned
accuracy - ANSWERcloseness of agreement b/n the measured value and true value
random error - ANSWERcauses variation in measured values found during repeated
measurements
systematic error - ANSWERcauses an offset b/n the mean value of the data set and
its true value
sequential test - ANSWERvaries the input value sequentially over the desired input
range
hysterisis - ANSWERrefers to the difference in the measured value b/n the upscale
sequential test and a downscale sequential test
what effect does calibration range have on interference? - ANSWERit tends to
reduce the effects of interference
linearity error - ANSWERa measure of the linearity error that arises in describing the
actual system behavior
sensitivity error - ANSWERa statistical measurement of the random error in the
estimate of the slope of the calibration curve
zero error - ANSWERshift in the calibration curve, with uncertainty (uz)- can be
reduced by zeroing
spectral resolution - ANSWERinterval between discrete frequencies
sensitivity - ANSWERthe error in the slope K of the calibration curve
measurand - ANSWERvariable to be measured
sensor - ANSWERfinds a measurable physical element with a property that changes
with variable to be measured
transducer - ANSWERfinds a way to make the sensor's change detectable -
transforms sensed info into a different form
signal conditioning - ANSWERimproves the system's ability to detect the signal-
modifies the signal to a desired magnitude and form
