Abstract : A SNOBOL4 program has been written which synthesizes the class of linear time-varying systems whose impulse response can be described by polynomials. The synthesis of linear time-varying systems which are described analytically involves the manipulation of algebraic functions in symbolic form; consequently, a system capable of performing algebraic and matric operations was required. The ALGEBRA 1 language provided a basis for the ALGEBRA 2 system used in this thesis. The ALGEBRA w system provides the algebraic and matric manipulation routines utilized by the Synthesis Program. The Synthesis Program has been designed so that it can be used by engineers who are unfamiliar with the SNOBOL4 language. The ALGEBRA 2 system, on the other hand, affords the SNOBOL4 programmer the additional capability of symbolic algebraic and matric manipulation. Users manuals for the Synthesis Program and the ALGEBRA 2 system, as well as example programs, have been included in the report. (Author)
