Millman & A. Grabel Microelectronics (ed. 2) vi. 223 The quantities NMH and NML correspond to the noise margins for V(1) and V(0), respectively... The significance of the noise margin is that an unwanted signal of amplitude less than NM will not alter the logic state. 1997 Electronic Engin. Times 30 June 10/5 He was confident that noise margins of 6 dB could be preserved. < as lemmas |
