Abstract
A first signal shaper generates a first signal having a first asymmetry. A second signal shaper generates a second signal having a second asymmetry different from the first asymmetry. The first and second signals have approximately the same peak-to-peak amplitude. An AC measurement element acquires a first scaled representation of the shape of the first signal and a second scaled representation of the shape of the second signal. A DC measurement element receives the first signal and the second signal and generates a first value responsive to the first signal and a second value responsive to the second signal. A processor calculates a first factor responsive to the shape of the first signal and a second factor responsive to the shape of the second signal. The processor applies the first and second factors and the first and second values in a function that generates the AC/DC cross-calibration coefficient.
