Claim Text:
1. An electromagnetic wave signal processor configured to process an input pulse signal corresponding to an electromagnetic wave, the electromagnetic wave signal processor comprising at least one signal processing unit, the signal processing unit comprising: a peak detecting circuit to detect peak values of each amplitudes of the input pulse signal; an AD converter to convert the peak values into digital signals; a memory device comprising a plurality of memory cells each of the memory cells having an address assigned in accordance with each of values capable of being taken by the digital signals of the peak values, and each of the memory cells being able to have any one of a plurality of internal states representing detection frequencies of the peak values and be changed among the plurality of internal states; and a writing circuit to change the internal state in the memory cell that has the address corresponding to the value of each of the digital signals converted by the AD converter, so as to increment the detection frequency represented by the internal state.
