Say you were...Recording music, assuming that human ears
can hear to 20kHz? what would be a MINIMUM frequency to
sample sound, according to Nyquist sampling theory? (enter
your number XXX in units of kHz, e.g. if you enter "9", it
represents 9 kHz) - Correct Answers ✅40 - The Nyquist
sampling frequency must be two times that of the maximum
audible frequency.

Update 2024)
What is the minimum Nyquist Frequency - Correct Answers
✅2 times the frequency of the signal to prevent aliasing.
What is the SUGGESTED Nyquist Frequency - Correct
Answers ✅About 10 times the signal frequency, but at least
5.
Say you were...Measuring the motion of a pendulum swinging
back/forth at 1 cycle per second... what would be a MINIMUM
frequency to sample the pendulum's position, according to
Nyquist sampling theory? (enter your number XXX in units of
Hz, e.g. if you enter "9", it represents 9 Hz) - Correct
Answers ✅2 measurements per second.
What are the three ways to handle the measurement of time?
- Correct Answers ✅1) Guestimate
2) Polling/Sampling
3) Interruption
Explain the Guestimate method for measuring time. -
Correct Answers ✅Using outside factors to infer the length
of time that has passed. (E.g. brightness outside, length of
each powerpoint slide)
