Class D amplifiers generally use a low-pass filter to attenuate the switching noise in the output waveform while passing the audio signal to the loudspeaker, but many engineers are not familiar with ...

This file type includes high resolution graphics and schematics when applicable. When designing filters, engineers very often need to know what the filtered value at the output will be. This is ...

As switch mode power supplies continue to increase the frequency at which they operate, the filter capacitor becomes more important. This guide gives some great insight into the selection and mounting ...
