METHOD, APPARATUS AND SYSTEM FOR SENSING A SIGNAL WITH AUTOMATIC ADJUSTMENTS FOR CHANGING SIGNAL LEVELS

摘要

The present specification provides a method, apparatus and system for sensing a signal with automatic adjustments for changing signal levels. A novel fractional peak discriminator circuit is provided which can be incorporated into a system for measuring periodic signals from moving elements. The circuit can be used regardless of whether the periodic signals are detected using optics, magnetic detector or other methods.
