By appropriate use of NOT gates 8, 8a and their associated switches 10, 10a for ensuring that inputs of the required polarity are always present at E 1 , E 2 , each of the sectors of the phase circle is scanned in turn, the output of the memory circuit 5 being a steady output in the absence of output pulses from gate 4a, i.e. if the vector Vc is not included in that sector and a pulsed output when the gate 4a produces an output pulse and the vector Vc is determined as lying in that sector. A calibrated phase shifter 11 enables the vector VR 2  to be moved precisely in relation to VR 1  and the phase of VC may thus be accurately determined. By the use of two similar devices such as shown in Fig. 9, but working on opposite alternations of the input quantities and by coupling the outputs of the memory circuits, a two level output with one level corresponding to the presence of the vector Vc may be obtained. In the embodiment of Fig.10 (not shown), the phase circle may be divided into small sectors by the use of n reference quantities, which are scanned sequentially by switching arrangement 12.
