Question

For a dynamic calibration involving a force measurement system, a known force is applied to a sensor. The force varies between 100 and 170 N at an angular frequency of

@= 10 rad/s.Find the average (static) value of the input signal, its amplitude and its frequency in Hertz.Assuming that the signal may be represented by a simple periodic waveform, express the signal, y(t), as a one term Fourier series. For 10 bonus points create an amplitude spectrum from an equivalent discrete time data set.
