Time-lag phenomena are significant in automatic control, magnetic circuitry, and elsewhere. From the mathematical viewpoint, these lead to differential-difference equations. The Memorandum shows how these equations can be treated, using a numerical procedure for inverting Laplace transforms. The study should be of interest to control and circuit engineers and to numerical analysts; it is also useful in treating wide classes of equations arising in biology, chemistry, operational research, and similar studies.

This report is part of the RAND Corporation Research memorandum series. The Research Memorandum was a product of the RAND Corporation from 1948 to 1973 that represented working papers meant to report current results of RAND research to appropriate audiences.
Our mission to help improve policy and decisionmaking through research and analysis is enabled through our core values of quality and objectivity and our unwavering commitment to the highest level of integrity and ethical behavior. To help ensure our research and analysis are rigorous, objective, and nonpartisan, we subject our research publications to a robust and exacting quality-assurance process; avoid both the appearance and reality of financial and other conflicts of interest through staff training, project screening, and a policy of mandatory disclosure; and pursue transparency in our research engagements through our commitment to the open publication of our research findings and recommendations, disclosure of the source of funding of published research, and policies to ensure intellectual independence.
