The paper presents an on-line digital signal processing method for active cancelation of distortion of sinusoidal sources. Generation of a sinusoidal signal of several volts is a simple task, but many measurements need high voltage, current, or non-electrical excitation. This signal conversion often leads to distortion. The proposed active distortion controller is a resonatorbased observer which determines the harmonic content of the signal, and the distorting components are subtracted from the
