GATE IN 2021 | Question: 35
A $4 \times 1$ multiplexer with two selector lines is used to realize a Boolean function $\text{F}$ having four Boolean variables $\text{X, Y, Z}$ and $\text{W}$ as shown below. $S_{0}$ and $S_{1}$ denote the least significant bit $\text{(LSB)}$ and most significant bit $\text{(MSB)}$ ... $F\left ( X,Y,Z,W \right )=\sum \text{m}\left ( 1,3,7,9,15 \right )$

The figure below shows the i $^{th}$ full-adder block of a binary adder circuit. C${_i}$ is the input carry and C${_i}{_+}{_1}$ is the output carry of the circuit. Assume that each logic gate has a delay of 2 nanosecond, with no additional time delay due to the interconnecting wires. If the inputs A${_i}$,B${_i}$ are ... stable throughout the carry propogation, the maximum time taken for an input C${_i}$ to produce a steady-state output C${_i}{_+}{_1}$ is $\_\_\_\_$ nanosecond.

A $4$ to $1$ multiplexer to realize a Boolean function $F(X, Y, Z)$ is shown in the figure below. The inputs $Y$ and $Z$ are connected to the selectors of the $MUX$ ($Y$ is more significant). The canonical sum-of-product expression for $F(X, Y, Z)$ is $\Sigma m (2, 3, 4, 7)$ $\Sigma m (1, 3, 5, 7)$ $\Sigma m (0, 2, 4, 6)$ $\Sigma m (2, 3, 5, 6)$
