In the circuit shown below, switch S1 and S2 are in open and close position respectively for long time. At $$t = t_o$$, switch S1 is closed and switch S2 is opened. What would be the current through R1 immediately after the transition of switches?
A digital board has a unipolar square clock of 250MHz. If the clock on the board at all places should have all the harmonic components which have more than 10% of DC value, the board has to be designed forat least
A radar system uses magnetron as high power RF source. Its transmitter emits 300kW RF power at 10% duty factor. If the efficiency of radar transmitter during pulse is 60% and the power required during pulse off period is 1 kW..The average power dissipation in radar is,
