Read the statements below concerning an OR gate. At first, they may appear to be valid, but after some thought you should realize that neither one is always true. Prove this by showing a specific example to refute each statement.

(a) If the output waveform from an OR gate is the same as the waveform at one of its inputs, the other input is being held permanently LOW.

(b) If the output waveform from an OR gate is always HIGH, one of its inputs is being held permanently HIGH.
