Indicate if the statement is true or false. If a statement is false, indicate the correct answer.
1. In vibration analysis, we often assume that an accelerometer signal is stationary. A
stationary signal has the property that the statistical properties of the signal do not change with time.
2. The error due to under-sampling a continuous signal can be avoided by simply
amplifying the signal.
3. The discrete Fourier transform (DFT) of a signal is periodic with period being a
function of signal sampling frequency.
4. Proximity or displacement sensors are commonly used to measure the movement of the shaft in a ball bearing.
5. Magnetic mounting is the best approach for mounting accelerometers on to bearing

In vibration analysis, we often assume that an accelerometer signal is stationary. A stationary signal has the property that the statistical properties of the signal do not change with time.
True stationary signals are statistically constant with time so, as an example, if you look at such a signal now and in an hour's time it would look statistically the same.
The error due to under-sampling a continuous ...
