ACTUAL QUESTIONS AND CORRECTLY WELL DEFINED ANSWERS LATEST
ALREADY GRADED A+ .
What is the relative effect of the quantization error of an ADC with 8-bits and a 0.420V analog signal.
The ADC has a full scale range of 0V to 3.3V. - CORRECT ANSWER-3.05%
What are the implications of a 3% relative effect of quantization error? - CORRECT ANSWER-3%
quantization error is low, so the input voltage will likely be able to be measured with reasonable
accuracy.
What is the phenomenon when the count of button presses recorded doesn't match the actual
number of button presses? - CORRECT ANSWER-bouncing
When captured using interrupts, we would expect the unfiltered recorded count of button presses to
be lower, higher, or the same as the actual count? - CORRECT ANSWER-Higher
Will the voltage values read from the Arduino exactly match the levels coming to the analog pin? -
CORRECT ANSWER-No
Sensors are: - CORRECT ANSWER-noisy, late, wrong
What is the voltage range(full scale range) for the Arduinos? - 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
, How many discrete numbers can an 8-bit ADC represent? - CORRECT ANSWER-256 discrete numbers
Compute the voltage resolution for an 8-bit ADC with a 0.420V analog signal. The ADC has a full scale
range of 0V to 3.3V. - CORRECT ANSWER-0.0128V
Find the quantization error of an ADC with 8-bits and a 0.420V analog signal. The ADC has a full scale

Imagine you have set up a voltage divider circuit that includes an RTD as one of the resistors. You are
reading in the Vout from the voltage divider using an analog pin of your Arduino.
If the Vout is 1.126V, what discrete number will the Arduino ADC return? - CORRECT ANSWER-230
Imagine you have set up a voltage divider circuit that includes an RTD as one of the resistors. You are
reading in the Vout from the voltage divider using an analog pin of your Arduino.
If the Vout is 1.126V, what voltage does this discrete integer represent? - CORRECT ANSWER-1.123V
What does the FTT(Fast Fourier Transform) analysis of a signal tell us:
A: Hints of how to design effective filters for processing recorded data
B: what the frequency content of recorded data is
C: Frequencies at which the signal is likely to be happening
D: the electrical impedance of each component of a circuit
E: Frequencies at which noise is likely to be happening - CORRECT ANSWER-A, B, C, E
You are measuring a sensor output with these attributes: a signal frequency of 50Hz(amplitude of 1.0),
noise at frequencies 2000Hz(amplitude 0.25), 5000Hz(amplitude 0.5), and 10,000Hz(amplitude 0.75).
If you ran a FFT on the sensor output, what frequencies would you see peaks at? - CORRECT
ANSWER-50Hz, 2000Hz, 5000Hz, 10,000Hz
In the frequency domain plot, what would the label of the x-axis be? - CORRECT ANSWER-Frequency
