In this video, I explain some theories behind a low pass active filter circuit, then I built a simple active low pass filter using the LM358 opamp. I examined the filter’s behavior using the Siglent ...
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 ...
Noise is a common and pervasive problem in electronics design and debug. At one time or another, almost every designer and debugger of electrical circuits will spend some time dealing with ...
