transmit and receive transformers side by side, sufficient crosstalk
attenuation is achieved by the inherent characteristics of the toroid
cores as well as by their proper positioning. The crosstalk attenua-
tion is typically 50 dB or better from 100 KHz to 10 MHz. This result
was established with the test circuit shown below.
