The Equivalent Selectivity of Transformer Coupled Loop-Antenna Input Circuits

摘要

The over-all or equivalent selectivity of the simple transformer-coupled loop-antenna circuit is considered. From the analysis, design criteria are obtained. Graphs of equivalent circuit Q are so presented that intermediate design values can be determined by interpolation. Conclusions are that the net over-all circuit Q may be somewhat higher than that of the loop antenna for low values of transformer coupling.
