without insertion of a length of waveguide give the insertion loss. Least-squares fitting of transmission versus frequency data have been used to determine Q and resonant frerluencyf, with cOmPutercontrolled equipment in an iterative process. Preliminary values of Q and j, are used to calculate an improved set of test frequencies, and so on. A rapid least-squares method is described which minL mizes truncation errors.
