Abstract
The numerical solution of field substructures in time domain diakoptics requires an interation time consistent with the numerical accuracy required. When storing and reconnecting the substructures, the information required can be obtained from considerably fewer samples. This paper shows how time domain approximations can further reduce the storage and computing time in space approximated time domain diakoptics.

The nature and significance of time-domain approximations needed for a diakoptic solution using transmissionline modelling (TLM) are examined. Truncation, filtering and repeated convolution of time responses result in severe restrictions in the accuracy of time-domain diakoptics. The frequency-domai
## The purpose of this paper is to present an extension of the method of leastsquares as applied to time domain approximation. A technique is developed by which one is able to match the initial time domain behavior of the desired impulse response while performing the usual least-squares approximatio
