The Boolean function realized by the logic circuit shown is

For the output F to be 1 in the logic circuit shown, the input combination should be

Match the logic gates in column A with their equivalents in column B.

A transmission line has a characteristic impedance of 50 $$\Omega $$ and a resistance of 0.1 $$\Omega $$/m. If the line is distortionless, the attenuation constant (in Np/m) is
