Abstract : An adaptive reference threshold detector for sensing a drop of predetermined magnitude in the level of an input signal from its peak value during an interval of time. A capacitor, diode coupled to the output of a voltage follower, is charged to a level coincident with the maximum input signal voltage during the time interval of interest. The voltage stored thereon is coupled through a negative feedback arrangement and resistive divider network to one port of a voltage comparator. The input signal itself serves as the second input to this voltage comparator circuit. A logic level signal is generated by this comparator when the difference between its two input port signals exceeds a predetermined value. (Author)
