1. A calibration system, comprising:
a waveform generator configured to generate a periodic waveform; and
a control circuit in signal communication with the waveform generator, wherein the control circuit comprises:
an analog-to-digital converter configured to convert the periodic waveform to digital values; and
an electronic device in signal communication with the analog-to-digital converter, wherein the electronic device is configured to utilize the digital values associated with one period of the periodic waveform to automatically verify the following:
a timing calibration of the control circuit is within a first predetermined threshold tolerance; and
a voltage level calibration of the control circuit is within a second predetermined threshold tolerance.
