Claim:
1. A circuit comprising: a transformer configured to provide an input signal, the input signal comprising an input signal amplitude characteristic and an input signal frequency characteristic; a pulse generator configured to generate a pulse signal, the pulse signal comprising a pulse signal amplitude characteristic and a pulse signal frequency characteristic; an analog-to-digital converter in electrical communication with the transformer and the pulse generator, the analog-to-digital converter configured to receive a combined signal comprising the input signal and the pulse signal, the analog-to-digital converter configured to convert the combined signal to a digital representation of the combined signal; a first digital filter in electrical communication with the analog-to-digital converter, the first digital filter configured to reconstruct the amplitude characteristic of input signal; a second digital filter in electrical communication with the analog-to-digital converter, the second digital filter configured to reconstruct the pulse signal; and a controller electrically connected to the first digital filter and the second digital filter, the controller configured to indicate at least one of a short or an open associated with the transformer based upon a value of the reconstructed pulse signal.
