A two-bit counter circuit is shown below



If the state Q${}_A$ Q${}_B$ of the counter at the clock time tₙ is ‘10’ then the state Q${}_A$ Q${}_B$ of the counter at tₙ + 3 (after three clock cycles) will be

A clipper circuit is shown below:



Assuming forward voltage drops of the diodes to be 0.7 V, the input-output transfer characteristics for the circuit will be

The input voltage to a converter is

$V_i=100\sqrt{2}\sin \left(100\pi t\right)V$

The current drawn by the converter is

$i_1=10\sqrt{2}\sin \left(100\pi t-\frac{\pi }{3}\right)+5\sqrt{2}\sin \left(300\pi +\times \frac{\pi }{4}\right)+2\sqrt{2}\sin \left(500\pi t-\pi /6\right)A.$
