Abstract

Conclusions: The shape factor of the first two sets of filter engineering samples deviates significantly from the requirement. This probably results from stray reactances and crystal static resistance but will be investigated more fully during the next quarter. It is unlikely, however, that the shape factor can be significantly improved from the performance of the second set of filters. A satisfactory method of final frequency calibration of the CR(XM-65)/U units has been developed and some progress has been made toward lowering static resistance. (Author)
