A digital logic element represents the high state with an output of between 2.8 and 2.95 V. The same logic element will see an input high state as a voltage in the range 2.1 to 3.0 V. What is the reason for this difference? What are the practical implications?
What will be an ideal response?
The output level for a high state is determined by the circuit of the gate and the electrical characteristics of the transistors. When a circuit is designed, the output high level is made as close to the high?voltage level in the circuit as possible. The range of inputs that are interpreted as a high level is made wider. This is done so that a high?level signal can suffer from some degradation due to noise and still be interpreted as a high level state. In this example, the lowest high?level output of a gate is 2.8V, whereas an input of 2.1V will be recognized as a high?level state. This means that a 2.1V output can be corrupted by noise or otherwise degraded by 0.7V and STILL be recognized as a high?level state.
