Signal combining apparatus

摘要

A signal combiner for combining two out-of-phase signals wherein one of these signals increases in amplitude over a range of frequencies at a rate of 6dB per octave. The resultant output signal obtained from the combiner appears to be that of two signals which are in-phase and have a constant ratio of amplitude therebetween. A specific application for this signal combiner is to combine the signals obtained from a sense antenna and from a loop antenna in an automatic direction finding device.
