In this technical paper, a measurement system for the frequency response measurement, in amplitude and phase, is shown. The system is based on the phasorial sum, and it operates in the frequency range from 10 Hz to 100 KHz. The phase is achieved by the amplitudes of the input and output voltages and by their phasorial sum; the phase sign is achieved by an electronic circuit, which is realized by a delay-type flip-flop. The system is controlled by a software, so that the input and output voltages of the device under test and their phasorial sum are sequentially measured by a switch and a digital voltmeter. Some meaningful measurements and simulations confirm the soundness of the proposed system.
