← Logic & PuzzlesWhich outcome occurs when a digital circuit design violates the principle of 'no floating inputs' and an input is left unconnected?
A)Predictable logic gate output
B)Unpredictable logic gate output✓
C)Decreased power consumption occurs
D)Reduced propagation delay develops
💡 Explanation
An unconnected input can randomly fluctuate due to electromagnetic interference, because this leads to an unpredictable voltage level being registered by the gate; therefore, the output becomes unstable, rather than providing a defined logic level like high or low.
