Question

prove the following boolean identity . A + A' B = A + B​

Answer 1

Answer:

+ 1 = 1 A in parallel with

closed = “CLOSED” universal parallel circuit Annulment

A + 0 = A A in parallel with

open = “A” universal parallel Identity

A . 1 = A A in series with

closed = “A” universal series circuit Identity

A . 0 = 0 A in series with

open = “OPEN” universal series Annulment

A + A = A A in parallel with

A = “A” idempotent parallel circuit Idempotent

A . A = A A in series with

A = “A” idempotent series circuit Idempotent
