The design of finite impulse response (FIR) filters remains a cornerstone of digital signal processing, with ongoing efforts to refine both the algorithmic and hardware aspects of their implementation ...

Second-stage output filters are often used to attenuate the output voltage ripple of a switching power supply. They can also isolate one load circuit from another. In this power tip, I will describe ...

Electromagnetic interference (EMI) has a reputation for being one the most difficult aspects in power-supply designs. I think that this reputation comes, in large part, from the fact that most ...

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 ...

Most environments are full of some type of electromagnetic interference (EMI). EMI can wreak havoc, or at a minimum, cause a circuit design to experience less-than-optimum performance. Designers may ...

Digital signal processors (DSPs) continue to receive a great deal of attention in new product design. For example, digital filter design reflects the importance of understanding and using this ...
