(a) contains a freewheeling diode Dm, commonly connected across an inductive load to provide a path for the current in the inductive load when the switch S is opened after time t (during which the switch was closed). Consider the circuit operation in two modes, with mode 1 beginning when the switch is closed at t = 0, and mode 2 starting when the switch is opened after the current i has reached its steady state in mode 1. Obtain the waveforms of the currents i(t) and if(t).
(b) Consider the energy-recovery diode circuit shown in Figure , alongwith a feed- backwinding.Assume the transformer to have a magnetizing inductance of Lm and an ideal turns ratio of a = N2/N1. Let mode 1 begin when the switch S is closed at t = 0, andmode 2 start at t = t1, when the switch is opened.
Let t1 and t2 be the durations ofmodes 1 and 2, respectively. Develop the equivalent circuits for the two modes of operation, and obtain the various waveforms for the currents and voltages.
Explain the delay model based on logical effort often used in estimating delays in logic cells. Hence use the model to predict the delay of a 4-input NOR logic cell with a 3 times

Give the register organization of 8257? The 8257 do the DMA operation over four independent DMA channels. Each of the four channels of 8257 has a couple of two 16-bit registers
Q. Two single-phase transformers, each rated 2400: 120-V, are to be interconnected for (a) 4800:240- V operation, and (b) 2400:120-V operation. Draw circuit diagrams and show polar
