In the $$4 \times 1$$ multiplexer, the output $$F$$ is given by $$F = A \oplus B.$$ Find the required input $${{\rm I}_3}{{\rm I}_2}{{\rm I}_1}{{\rm I}_0}.$$

The figure shows a digital circuit constructed using negative edge triggered $$J-K$$ flip flops. Assume a starting state of $${Q_2}\,{Q_1}\,{Q_0} = 000.$$ This state $${Q_2}\,{Q_1}\,{Q_0} = 000$$ will repeat after _____ number of cycles of the clock $$CLK.$$

An $$8$$-bit, unipolar Successive Approximation Register type $$ADC$$ is used to convert $$3.5$$ $$V$$ to digital equivalent output. The reference voltage is $$+5 V.$$ The output of the $$ADC,$$ at the end of $$3$$rd clock pulse after the start of conversion, is

The voltages developed across the 3Ω and 2Ω resistors shown in the figure are 6V and 2V respectively, with the polarity as marked. What is the power (in Watt) delivered by the 5V voltage source?
