Question

In the microprocessor controlled measurement scheme shown in the figure, Rx is the unknown resistance to be measured, while Rref and Cref are known. Cref Is charged from voltage VL to VH (by a constant DC voltage source VS ), once through Rref in Tref seconds and then discharged to VL . It is again charged from voltage VL to VH through Rx in Tx seconds.
