A signal analyzer system comprises a differential operator configured to receive at least one input signal, and to determine at least one locus based on instantaneous differences in a relative rate of change between the at least one input signal and the at least one input signal's at least one n<SUP>th</SUP>-order derivative, wherein n represents at least one selected order of differentiation. A distortion identifier is configured to compare at least one amplitude of the at least one determined locus against at least one selected reference locus, and to identify at least one distortion in the signal when the comparison indicates at least one selected exception condition.
