Figure 2[a] shows an electrical signal resembling a sawtooth
wave.
If the vibration signal as expressed in the equation is
sampled at 5000 Hz,
(i) determine the false frequency(ies) that might exist
(ii) determine the minimum sampling frequency that
might resolved all harmonic components as expressed in the
equation.
