An application of a multiplexer is in a parallel-to-serial data converter. By putting 8 bits of data on the input lines of the multiplexer and then stepping the select lines sequentially from 000 to 111 , the 8 bits of data are put onto the output line in series. A typical use for parallel-to-serial conversion is in a keyboard, where each keyboard stroke implicitly defines a 7- or 8-bit number that must be output over a serial link, such as USB. [10] 3. The block diagram below is a three-input, two-output combinational switch circuit. If $s$ is 0 , the input a is routed directly through to $x$, and $b$ is routed to $y$. If $s$ is 1 , they are switched, with a being routed to $y$ and $b$ to $x$. Construct the circuit using only AND, OR and NOT gates. $[10$ 1. Given the following logic circuit, what function does this circuit implement? $F(x,y,z)=$ Construct the truth table for this logic diagram.
