In this article, I’ll describe a few easy steps that will convert any Sallen-Key (SK) or multiple feedback (MFB) active filter from a single-input filter to a summing active filter that gives the same ...

Most oscilloscopes are fitted with filters to help improve measurement by reducing overall noise in an acquisition to improve signal-to-noise ratio (SNR). Even the most basic oscilloscopes include an ...

Binary search, a decrease-and-conquer approach, plays an important role in testing today�s low-pass filters. When testing a low-pass filter, generally you have to use an arbitrary waveform generator ...

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 ...

Any pointers to good resources on audio filters for WAV files (particularly low-pass filters) implemented in Java? I've found a goodly amount of resources on DSP and filters, but when it gets to ...

Entry-level oscilloscopes are a great way to get some low-cost instrumentation on a test bench, whether it’s for a garage lab or a schoolroom. But the cheapest ones are often cheap for a reason, and ...
