All steps pls, thanks

1. (10 Points) Describe how each of the following circuits works. ) a Decoder b) Multiplexer 2. (25 Points) Assume you have the following truth tables for functions F1(w,x,y,z) and F2(w,x,y,z): F1 0 0 NO 0 w 0 0 0 F2 0 1 1 1 0 0 0 1 0 0 0 0 0 1 1 0 0 0 0 1 0 1 1 0 0 1 0 0 1 0 1 1 0 0 0 0 1 1 1 0 0 0 1 0 0 0 0 1 1 1 0 0 0 1 1 1 0 0 0 0 0 1 1 0 1 1 0 1 0 1 1 1 1 1 1 1 0 1 1 1 0 1 1 1 1 1 1 1 1 a) (10 Points) Express F1 and F2 in sum-of-products form. b) (10 Points) Simplify each function. c) (5 Points) Draw one logic circuit to implement the above two functions
