Introduction:

This Bulletin is offered as a guide to engineers involved in the design of consumer entertainment audio products and television receivers.

Because of the proliferation in the past few years of RF transmitting equipment (AM, FM, TV, radar, radio amateur, Citizens Band, etc.) it is a necessary requirement of good equipment design to engineer circuits with built-in interference rejection.

Original equipment manufacturers can no longer expect the serviceman to correct normal type interference problems in the field. The cases are becoming too frequent and the cost of correction too high to ignore this interference in the original design.

The Bulletin is intended as the first step toward developinga standard method of measurement covering specific techniques.
