PROBLEM TO BE SOLVED: To obtain a highly accurate timestamp.SOLUTION: An electronic device of this embodiment includes: a threshold determination part; a plurality of comparator circuits; a time digital conversion circuit; a low pass filter part; an analog digital conversion circuit; and an energy calculation part. A threshold determination part dynamically determines a plurality of thresholds. Each comparator circuit compares the corresponding threshold with an analog input signal. The time digital conversion circuit outputs a plurality of time values by outputting the time values when the analog input signal matches to a threshold of the plurality of thresholds, or when the analog input signal exceeds the threshold. A low pass filter part is adjustable, and filters the analog input signal. The analog digital conversion circuit performs analog to digital conversion to the filtered analog input signal to generate a digital signal. An energy calculation part calculates energy of the digital signal in response to reception of a trigger signal.
