[20 points] Draw a circuit that multiplies a 4bit unsigned binary number X3 X2 X1 X0 by a 3bit unsigned binary number Y2 Y1 Y0, using an array of fulladder cells. Determine the worst case propagation delay if each full adder takes 10 ns to produce its C and S outputs, and each AND gate (used to generate the product components) has 10 ns of propagation delay. C S X Y Z full adder cell to use X3 X2 X1 X0 × Y2 Y1 Y0 Name: __________________________________________ Class No: __ __ __ __  __ Signature: ______________________________________ Score: _______ / 40 Your Class No. is the last four digits of your PUID followed by the first character of your last name....
