5-2. A logic gate noise margin parameters are:

VIH = 1.6 V, VIL = 0.3 V, VOH = 1.7 V, and

VOL = 0.2 V.

(a) Calculate NMH-

(b) Calculate NML.

(c) The input voltage is down to 1.7 V and a

negative 50 mV noise spike appears. What

happens to the circuit fidelity?

(d) The input voltage is down to 1.7 V and

a negative 150 mV noise spike appears.

What happens to the circuit fidelity?
