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?
