1. A method implemented on a computer having one or more processors and one or more memory devices, the method comprising:
receiving an input signal in the form of a digital waveform signal, wherein the input signal comprises a plurality of amplitude values, and each amplitude value having a corresponding time value; selecting, by a measurement engine, a series of overlapping time windows from the input signal, wherein each window has a beginning and an end, thereby defining time slices each indexed by an integer M, wherein a given time slice is a difference between the beginning of one window having index M and that of another having index M−1, or the difference between the end of one window having index M and that of another having index M−1; transforming, by the measurement engine, using a decaying exponential windowing function on each time window in the series of overlapping time windows, the corresponding time and amplitude values into a plurality of transformed amplitude values, each associated with a corresponding frequency, to thereby form a first matrix indexed by the time slices and frequencies; performing, by the measurement engine, time-domain deconvolution on the plurality of transformed amplitude values for each frequency index to thereby form a second matrix of deconvolved amplitude values indexed by the time slices and frequencies; determining, by a comparing engine, a plurality of maxima and minima values in the second matrix; marking, by a marking engine, the determined plurality of maxima and minima values to thereby form a measuring matrix indexed by the time slices and frequencies; and outputting the measuring matrix to thereby reveal information associated with the input signal, wherein outputting includes at least one of storing, displaying, or transmitting the measuring matrix; and wherein the engines are implemented using the one or more processors of the computer. |
