Abstract :
Conception of multiterminal nullator as a new singular element, has been presented. It was employed for nullator/norator analogue model of a multiplier. Nullator models of floating voltage controlled current source with controlled transmission conductance, have been also shown. Their electronic realisations containing analog multipliers, transistor current mirrors as well as differential difference operational amplifiers, have been presented. Basing on them, controlled floating admittances are realised. For example, synthesis of floating power source controlled by product of voltages, as an active non-linear circuit, has been carried out
