Abstract:
An apparatus for dynamically detecting energy of each one of a plurality of incoming signals received from a detector, without pile-up of previous ones of said plurality of incoming signals, comprising:a delay circuit connected to receive an incoming signal from said detector, said delay circuit passing said incoming signal from an input to an output of said delay circuit after a time delay; a trigger circuit connected to receive said incoming signal from said detector, said trigger circuit generating a triggering signal upon receipt of a subsequent one of said plurality of incoming signals at said trigger circuit; a computation circuit connected to said output of said delay circuit, said computation circuit determining a weighted value of said incoming signal; a sampling circuit connected to receive said weighted value from said computation circuit, said sampling circuit passing said weighted value from an input to an output of said sampling circuit upon receipt of said triggering signal; and a residual subtraction circuit connected to said output of said sampling circuit, said residual subtraction circuit subtracting a residual signal value corresponding to a residual weighted value of said previous ones of said plurality of incoming signals, said residual subtraction circuit providing an output signal corresponding to said energy of said incoming signal.
