CERTIFICATION SUCCESS 2026
Sensors can be... - correct-answer -noisy, late, and wrong
What is the voltage range (a.k.a. full scale range) of your Arduino? - correct-
answer -5 V
How many bits does the Arduino ADC have? - correct-answer -10 bits
What is the voltage resolution of the Arduino? - correct-answer -0.004883 V
,2|Page
What is the Nyquist rate that you will need to adequately sample the signal?
(Hint: to pick the correct equation from Lecture 6, you can pay close attention to
the question's wording and/or think about what you know in the system. Think -
is it the characteristics of the data input device or the signal?) - correct-answer -
50 Hz, 2000 Hz, 5000 Hz, 10000 Hz.
100 Hz
What is dead reckoning? - correct-answer -Estimating position using past position
in combination with velocity estimates
What is a cutoff frequency? - correct-answer -The value at which a filter 'takes
effect' and begins to attenuate frequencies
Let us return to the scenario from last week's quiz, in which you were
hypothetically measuring a sensor output with these attributes: a signal
, 3|Page
frequency of 50 Hz (with an amplitude of 1.0), and noise at frequencies 2000 Hz
(amplitude 0.25), 5000 Hz (amplitude 0.5), and 10000 Hz (amplitude 0.75).
You plan to filter out the noise frequencies that are higher than the signal
frequency using a filter. What cutoff frequency from the list below is the best
choice for this task, of the responses provided? (Note: for this task, there is no
universal correct answer, but Bode plots show that some answers are better than
others. Online forums also have advice on how to select cutoff frequencies.)
To achieve the filtering described in the question above, which type of filter
circuit would you use?
If you only have 0.1 μF capacitors lying around, what value of resistor would you
need to achieve the cutoff frequency - correct-answer -1000 Hz
low-pass
1592 Ω
