NOISE CONSIDERATIONS IN DIGITAL SYSTEMS

Date Issued:
1978
Summary:
The use of digital circuits in incre asingly diverse applications and environments has greatly increased the probability of electromagnetic interference in digital machines. The source and control of noise in digital systems have become major considerations in hardware design. This paper addresses these problems and their solutions. The noise immunities of various semiconductor families are compared showing design tradeoffs. The effects of transmission line reflections on digital wave forms are analyzed. The means for calculating interference between conductors (crosstalk) are shown with appropriate approximations. The effects of shielding conductors and circuitry are explored with formulas for near field calculations shown. Proper grounding and power supply decoupling methods are shown to be paramount to proper system design. The paper ends with an approximate noise analysis of a simple computing machine.
