Question

What is clamping circuit theorem? Derive an expression.

Answer 1

THE CLAMPING CIRCUIT THEOREM

This theorem enables us to calculate the voltage level to which the output is clamped by considering the areas above and below the reference level, when the values of Rf and R are known.

The clamping circuit theorem states that under steady-state conditions, for any input waveform, the ratio of the area under the output voltage curve in the forward direction to that in the reverse direction is equal to the ratio Rf/R. To prove the clamping circuit theorem, consider a typical steady-state output for the clamping circuit

The expression for the clamping circuit theorm is:

Af/Ar=Rf/R
