ABSTRACT:
An apparatus for detecting a relative displacement between a scale and a head is disclosed in which an equilibrium modulated signal derived from at least one detecting head is processed and converted into a DC voltage signal, a level of the DC voltage signal indicating the relative displacement of the scale to the head. At least one sample-and-hold circuit (its sampling time is synchronized with a reference signal, i.e., an excitation signal supplied to the head) or peak/hold circuit and low-pass filter (smoother) is used to provide the DC voltage signal.
