Circuit for the real time analysis of the energy distribution of pulses of a pulse signal

A circuit for the real time analysis of the amplitude of the pulses of a pulse signal, said analysis comprising counting the pulses appearing in each of a plurality of windows of energy, said circuit comprising:

• an analog-digital converter means receiving said pulse signal and supplying for each pulse a digital signal which is a function of the amplitude of said pulse,
• a memory means having locations, said memory means being addressed by said digital signal, each location containing a code indicating the window of energy corresponding to the amplitude of the pulse signal which corresponds to said location, said memory means supplying the code memorized in the location addressed by said digital signal,
• a decoder means having an input and a plurality of outputs, said decoder means receiving on said input said code from said memory means and supplying a signal on one of said outputs as a function of said code,
• a plurality of counting means, each counting means being connected to one output of said decoder means, and having means for storing the number of signals received from said decoder means.
