In the circuit shown in Figure, the source I is a dc current source. The switch S is operated with a time period T and a duty ratio D. You may assume that the capacitance C has a finite value which is large enough so that the voltage. has negligible ripple. Calculate the following under steady state conditions, in terms of D, I and R.
