Tame SMPS Noise: Easy High-Frequency Filtering Tips
The Problem : Switched-mode power supplies (SMPS) are compact and efficient, but they generate high-frequency noise that can interfere with nearby circuits—especially in audio systems, microcontroller boards, or sensitive analog devices. This unwanted noise often appears as glitches, screen flicker, or humming in speakers.
The Solution : To control …
