Development of an Improved Radio-Frequency-Filter System, for Model RDZ/RDZ-1 Receving Equipment

摘要

This report covers the development of a substitutive filter sys¬tem for the RDZ/RDZ-1 receivers in which the major deficiencies have been improved to the extent permitted by existing space limi¬tations and current availability of suitable components. As a result of the modifications described herein, the overall average protection against r-f energy introduced through the remote-line connections to the Model RDZ/RDZ-1 receiver has been increased to 112 deci¬bels;i.e., an overall improvement of 59 decibels has been attained.
