Abstract

Linear parametric circuits are circuits whose dynamics are governed by linear differential equations having at least one time-varying coefficient. Under certain conditions, oscillations are induced in such circuits. During the oscillation, if variations in the erstwhile constant parameters of the circuit is made to depend on some external causes, then the oscillation voltage will experience modulation. By appropriate demodulation of the oscillation voltage, changes due to the external cause are transduced to obtain the desired signals for measurement, control or other purposes
