digital electronics logic family, Electrical Engineering

Assignment Help:

For a given logic family, consider VOL = 0.25V and VOH = 5 V . For a given circuit, VIL = 0.96 V and VIH = 2.18 V. Find the largest positive-going and largest negative-going noise spike that can be tolerated. Also find the transition width and logic swing value. Is the given circuit functionally better than a circuit with VIL = 0.7 V and VIH = 2.81 V ??
