For an AND-OR circuit with an output expression AB + AB, determine the 1 andO combinations of input variables that make the output a 1. Draw the logic required for this expression.

3. Write an expression that is a 1 when one or more of its variables (A, B, and C) are Os. 5.Find the values of the variables that make each product term 1 and each sum term 0.

Eliminate the exclusive-OR, and then factor to obtain a minimum product of sums: (a) D'B'+ (DCA) (b) CB+(AB) C'+A'B Simplify each of the following expressions: A'D'(B+C)+(B+C)A'D+(B+C)(B+C) (a) (b) A'B'+A'C'+B'D'+B'C+DC (c) CB+BA+B'A'

2.67 please. My professor said to use a kmap, but I havent figured it out

3-) Analyze the circuits below and write the Boolean equation for each Part. Simplify the equation using Boolean algebra and determine if they function as an XOR, XNOR or neither. A): Dor B): XD XD . D

Design a code converter that converts a decimal digit from BCD to excess-3 code, the input variables are organized as (A B C D) respectively with A is the MSB, the output variables are organized as (W XY Z) respectively with W is the MSB, put the invalid decimal numbers as don't care. W=A+BD+BC' W=A+BD+BC, W=A'+BD+BC W= BC'D'+B'D+B'C

Problem 1 Find the expression for the output function, F. Do not simplify. B bar A bar #4 A B bar 0 Vdd- B C A bar

looking for assistance with these problems, mostly making sure i am correct and where i really need to study more.

14. a) Design an adder/subtractor circuit with one selection variable s and two inputsA and B.When s=0, the circuit performs A+B and when s=1 it performs A-B, by taking 2's  complement of B.b) Explain the design of status register.

Digital Logic Design   Using K-map derive the minimum SOP expression for each of the following functions: (a) F = ab’c’ + ab’c + abc’ +abc(b) Q = c' + cd + ac + a'bc'd + abc
