Consider the following logical expressions where A + B denotes A logical OR B, AB denotes A logical AND B, and ¯ A denotes inverse of A. Derive at least one additive (to be added by logical OR operation) term (excluding obvious 0, 1, A ¯ A or similar) which will not affect the result of the expression. For example, adding (by means of logical OR) term B C D to AB C+ ¯AB D does not change the result,...
