Active filters are ubiquitous in electronic design today, performing signal-frequency manipulation and conditioning for audio, IF (intermediate frequency), and digital-signal processing. The success ...

Several manufacturers offer op amp-based filter design tools [1-3]. Some tools choose off-the-shelf capacitor values, but others select non-standard ones. The option to alter passive component ...

Wideband filters with bandwidths in excess of an octave can be created by cascading a high-pass filter and a low-pass filter. In this design idea, nine-pole high-pass and low-pass filters have been ...

Prior knowledge needed: ECEA 5700 Introduction to Power Electronics, ECEA 5701 Converter Circuits, ECEA 5702 Converter Control, ECEA 5703 Magnetics Design, ECEA 5705 Averaged Switch Modeling and ...

Listen to the pop, sizzle, and hum. Look at the bars and wavy lines. These and other characteristics of electromagnetic interference (EMI) are very familiar. RF energy is radiated from a culprit ...

Low-pass filters (LPFs) are fundamental components in modern electronic systems, serving to permit signals below a designated cutoff frequency while attenuating higher frequencies. Recent advances ...

We bet when [devttyS0] made his latest video about RF filter design (YouTube, embedded below), he had the old saying in mind: in theory, there’s no difference between theory and practice, but in ...

SOFTWARE/HARDWARE: Texas Instruments Inc. introduced the latest version of its popular FilterPro™ design tool. FilterPro v3.0 offers a new and improved user interface and a more accurate and robust ...

When failure is not an option, high reliability EMI filters deliver superior high-frequency EMI suppression for ...
