2.4 Piezoelectric sensors work only for the time-variant force. 2.5 One can use Fourier series expansion to obtain the frequency spectrum of a periodic signal. 2.6 The frequency response function is a special case of the transfer function 2.7 If a sensor does not need any external source of power for its operation, it is called active sensor.
