Discusses the possibility of application in measuring instruments-analysers impedance along with sinusoidal test signal simple polyharmonic signals of the pulse type of optimization process for impedance measurement in the frequency range in order to improve the speed and accuracy.

impedance measurements, phase-sensitive detection, polyharmonical test signal, amplitude-frequency characteristic.
