Answer Posted / pradeep
Noise margin simply means margin for noise. it can tolerate
some amount of noise. The senders must be held at higher
standards than the receivers. For a 5V level, a voltage
above 4.5V is considered 1, and for receiver the voltage
above 3.5V is considered 1. therefore, the noise margin
4.5-3.5=1V.
it is deigned by looking at voltage transfer function.
