Prevention and Suppression of RF Interference to Audio Systems

By Jim Brown

In this study, the author builds upon Muncy's research, demonstrating that radio-frequency current on cable shields affects audio systems through the pin 1 problem and shield-current-induced noise (SCIN). An enhanced equivalent circuit for ferrite chokes is proposed, addressing dimensional resonance and inductor self-resonance. Field tests confirm that chokes reduce interference across 500 kHz to 1,000 MHz. Guidelines for diagnosing and mitigating EMI from various sources are provided for product development and field installations.
