2. (6 points) A digital logic unit consists of 3 input signals A, B, and C respectively and an output signal F. Design a logic circuit (that is, obtain the truth table -> draw the kmap and the logic circuit for the output signal F) for the corresponding logic unit that controls the passage of an input signal B, meeting the following requirements: Requirement 1: Output signal F is equal to B when input signals A and Care the same. Requirement 2: Output signal F is HIGH(1) when input signals A and C are different. Input signal A Input signal B Digital Logic Unit Output signal F Input signal c
