WebWhat is high noise margin? 2.2. Noise margin is a measure of design margins to ensure circuits functioning properly within specified conditions. … The noise margin, NM H = V OHmin V IHmin, for logical high is the range of tolerance for which a logical high signal can still be received correctly. Why is CMOS immune to noise?
Web20dB-30dB is excellent. 30dB-40dB is very good. 40dB-50dB is good. 50dB-60dB is poor and may experience connectivity issues. 60dB or above is bad and will experience connectivity issues. The standard signal attenuation spread for a given speed is somewhere in the region of 15-20dB for ADSL2/2+ speeds and 25-30dB for ADSL1 speeds. There are two noise margins to consider: Noise margin high (N MH) and noise margin low (N ML ). N MH is the amount of voltage between an inverter transitioning from a logic high (1) to a logic low (0) and vice versa for N ML. The equations are as follows: N MH ≡ V OH - V IH and N ML ≡ V IL - V OL.
