Lecture: Combinational Circuits An 8×1 multiplexer has inputs w, x, and y connected to the selection inputs S₂, S₁, and So, respectively. The data inputs I through I, are as follows: 1₁ = 1₂ = Z, lo = I₁ = 0, 13 = 16 = I₁ = z', and 15:= 1. Determine the Boolean function that the multiplexer implements (in brief notation).

2. Consider the function f (W₁, W₂, W3) = Σm(0, 2, 3, 6) use Shannon's expansion to derive an implementation using a 2-to-1 multiplexer and any other necessary gates.
Task: DL34. In digital electronics, a NAND gate (NOT-AND) is a logic gate which produces an output which is false only if all its inputs are true; thus, its output is complement to that of an AND gate. A LOW (0) output results only if all the inputs to the gate are HIGH (1); if any input is LOw (0), a HIGH (1) output results. A NAND gate is made using transistors and junction diodes. Minimum number of NAND gates required to implement the following binary equation (A'+B') (C+D)?

Draw 5 circuits using a 4x1 multiplexer that is the only enable signal of the function F (a, b, c, d) = ∑ (0, 1, 3, 5, 8, 13). Draw 2 circuits using an 8x1 multiplexer and a 2x1 multiplexer to enable the function F (a, b, c, d) = ∑ (1, 2, 3, 5, 7, 11, 13). Draw a circuit that performs F (a, b, c) = a'.b'.c '+ b'.c using only a 1x2 decoder with the least active-0 enable signal. (The information that the enable signal is 1 behaves like normal decoder where all outputs are 0, 0.)
