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 attenuation is typically 50 dB or better from 100 KHz
to 10 MHz. This result was established with the test circuit shown below.
