A spectrographic analyzer of pulses within a signal includes a data interface, an edge detection filter, a delay buffer, an integrator, and a histogram buffer. The data interface duplicates a stream of digital amplitude samples for the signal into a first and second stream. The edge detection filter determines the beginning and end of each pulse within the first stream of the digital amplitude samples. The delay buffer delays the second stream by a duration sufficient for the edge detection filter to determine both the beginning and end of each pulse. The integrator sums a respective amplitude total for each pulse. The respective amplitude total sums the digital amplitude samples between the beginning and end of each pulse in the second stream as delayed by the delay buffer. The histogram buffer maintains bins and increments a respective one of the bins encompassing the respective amplitude total for each pulse.
A spectrographic analyzer of a plurality of pulses within a signal, comprising:
