Question $2.$

Design a serial parity generator circuit that has two inputs; X $($the serial input$)$ and O $($the required type of parity; ODD$/$Even$,1$ for ODD and $0$ for Even$),$ and one output P $($will always be the parity bit for the input stream on X according to the type of specified by O$).$ e$.$g$.$ if O$=1,$ P $=1$ whenever the received sequence has even # of $1$s $($i$.$e$.$ to make their number ODD$),$ and P $=0$ whenever the received sequence has ODD # of $1$s$.$ If O is set to $0,$ then P $=1$ whenever the received sequence has ODD # of $1$s $($i$.$e$.$ to make their number Even$),$ P $=0$ whenever the received sequence has even # of $1$s$.$
