PART $1$:

Parity Bit Generator

YOUR TASK $-$ Create a circuit that takes four inputs $($D$8,$ D$4,$ D$2,$ D$1),$ presumably from binary switches, and generates the $3$ parity bits for this code. Your final design should look like the encoding block below.

HINT: If you need to XOR three or more variables, $\backslash ($ X $\backslash$oplus$($Y $\backslash$oplus Z$)\backslash$equiv X $\backslash$oplus Y $\backslash$oplus Z $\backslash ).$ This means that you can chain multiple XOR gates together to get the same result as$,$ say, a $3-$input XOR.
