Abstract
A device and method for conditioning a periodic analog signal to predetermined positive and negative desired peak values. The signal is adjusted using multiplicative correcting steps, which modifies the signal amplitude. An additive correcting step adds to the signal, a constant which adjusts the signal level in a positive or negative direction. Upon detection of a current actual peak value, the difference between the actual peak value and the predetermined desired peak value is stepwise reduced by repeated adjustments of the signal using modifying steps within a part of a period of the signal, each modifying step includes exactly one multiplication and exactly one additive correcting step.
