Suppose a signal from a vibrating motor is to be sampled discretelywith a digital data acquisition system to determine the RPM of the motor. It is known that the maximum possible RPM is 1800.

A. What is the minimum sampling frequency (in Hz) with which thesignal can be sampled in order to measure the RPM of the motor?
From Nyquist criterion, the sampling frequency fs must begreater than 2fmax so fs > 60 Hz.

B. For the same conditions above, suppose that the RPMneeds to be known to within a precision of +1 RPM. Calculate the minimum number of discretely sampled data points necessary to achieve this resolution.
