Abstract

Systems, apparatus, articles of manufacture, and methods are disclosed to generate a pulse waveform from a tachometer signal. An example apparatus disclosed herein includes machine readable instructions, and programmable circuitry to at least one of instantiate or execute the machine readable instructions to access a signal output by a tachometer monitoring machinery having a rotating component, determine, based on a first property of the signal, a first pulse threshold candidate for the signal, determine whether the first pulse threshold candidate satisfies a testing criterion, generate a second pulse threshold candidate after determining the first pulse threshold candidate does not satisfy the testing criterion, the second pulse threshold candidate based on (1) a second property of the signal or (2) a modification to the first pulse threshold candidate, determine whether the second pulse threshold candidate satisfies the testing criterion, and generate a pulse waveform based on the second pulse threshold candidate after determining the second pulse threshold candidate satisfies the testing criterion.
