Draw the truth table and logic circuit of a half-adder.

Number of 2:1 multiplexers required to design a 256:1 mux is ____.

Write the difference between combinational and sequential circuits.

Number of 2:1 multiplexers required to design a 256:1 multiplexer.

Implement the function: $$F(A, B, C) = \Sigma m(0,1,2,3,7)$$

Simplify $Y = ABC + A'BC + AB'C$.

A logic circuit has four inputs $A, B, C, D$ and output $Y$. $Y = 1$ when $A$ and $B$ are both 1, subjected to the condition that $C$ and $D$ are both low or both high. Design the logic circuit.

Simplify: $$Y = ABC + AB'C + A'BC$$

Design a logic circuit with inputs A, B, C, D and output Y, where Y = 1 when A and B are both high, and C and D are either both low or both high.

Design an 8-to-3 line Encoder circuit.

Find the simplified logical expression for:

$$Y(A,B,C,D,E) = \Sigma m(0,2,4,7,8,10,12,16,18,20,23,24,25,26,27,28)$$
