step by step please
b) (4 marks) In the following circuit (Figure 1) the decoder (DCD) has two inputs and four (active high) outputs. The three multiplexers (MUX) each have two select inputs (shown on top of the box) and an active high enable input (shown on the bottom of the box). Inputs A, B, C, D are select inputs; inputs \( \mathrm{N} \) through \( \mathrm{Z} \) are data inputs. Fill in the following truth table for the circuit giving the value of output \( F \) for each of the 16 possible select combinations. Figure 1
