Abstract : The analog (or digital) computer solution of a linear differential equation of the form L(D)y(t) = M(D)u(t) is invariably obtained by solving an equivalent set of linear firstorder differential equations. It is shown in this Report that if the polynomials L(D) and M(D) have a common factor, this equivalent set of firstorder equations must be chosen in a particular manner. The initial conditions associated with the equivalent firstorder system are intimately related to the given initial conditions on y and its derivatives. The fundamental equation embodying this interrelation is developed. (Author)
