A 3-to-8 decoder can be built using two 2-to-4 decoders plus some basic logic gates as shown in the following figure: Wo Wo Yo Yo W1 Y2 Y2 W2 En Уз Уз En Wo Yo Y4 Y5 Y2 Y6 En Уз Y7 create a truth table for the 3-to-8 decoder.

Use digital gates and minimum adder blocks to calculate A2 +3Bwhere A is a 2-digit and B is a 3-digit unsigned binary numbers.   Please draw this by hand and not AI

Assume that the system has eight 2-bit data inputs, A=a1a0, B=b1b0, C=c1c0, D=d1d0, W=w1w0, X=x1x0, Y=y1y0, Z=z1z0. There are also 2 control bits s1s0. The system computes A+B, C+D, W+X, and Y+Z when s1s0 equal to `11', `10', `01', `00', respectively. Use 1-bit 2-to-1 multiplexers and a 2- bit adder to implement this function. Please show how the inputs, multiplexers, and adder are connected. Label the inputs and select signals clearly. You don't need to show the details of the adder. (Hint: The adder has two 2-bit inputs E=e1e0 and F=f1f0. Each of E and F is generated by a 2-bit 4-to-1 multiplexer, which can be built using 1-bit 2-to-1 multiplexers.)
