Ansewr the following Questions:
Use the data from the two sets, set 1(in red) and set 2(in black) after the questions.
1. Two data files will be provided for analysis. Each file contains one block of a discrete signal sampled from an accelerometer (acceleration in gpk). The files are named "Set1.txt" and "Set2.txt". Provide the following information for each data set:
a. What is the sample frequency (fs) for each signal?
b. What is the δt for each signal?
c. What is the block size (N) for each signal?
d. What is the frequency resolution for each signal (δf)?
e. What is the block time (T) for each signal?
f. Plot each signal in the time domain.
2. Plot a FFT for each signal (amplitude units of gpk).
a. Inspect both FFTs. What frequency components are these signals comprised of?
b. What are the respective magnitudes (gpk) for each frequency component (for both Set1 and Set2)?
c. What is the difference in magnitude (if any) for each respective peak when comparing the FFT of Set1 to Set2?
d. For both signals (Set1 and Set2), determine the number of integer periods for each frequency component that will occur within the block time T.
3. For each signal, plot an FFT with amplitude units of mils pk-pk.
4. If this data was acquired on a machine operating at a speed of 1200 RPM, construct an order spectrum plot for each signal with amplitude units of acceleration in gpk.
