The report discusses various techniques of designing auto-adaptive self-changing filters, and the application of one particular technique to two teleseisms. This report also discusses the calculation of running correlation functions using a moving time window, and iterative solutions to the multi- channel normal equations. A program listing is included in the Appendix which will calculate an auto-adaptive multi-channel filter by the use of running correlation functions and the method of steepest descent.
