In this video, I used the bode plot to analyze the low pass active filter’s behavior in practice. There are not many devices that can calculate and demonstrate the bode plot. I used Siglent SDS2102X ...

Editor’s note: My good friend and long-time colleague, Michael Steffes, expands upon my introduction article, Rauch filter basics, and adds some very useful and practical insights into the Rauch ...

An easy way to conceptualize active filters is thinking about audio speakers. A speaker crossover has a low-pass, high-pass and band-pass effect breaking a signal into three components based upon ...

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 ...

Active filters and advanced signal processing techniques are at the forefront of modern electronic system design, enabling precise manipulation of analogue signals for a variety of applications. Owing ...

For many analog-to-digital converter (ADC) applications, a simple passive resistor/capacitor (RC) filter at the buffer input will provide adequate antialiasing filtering. However, an active filter is ...

Today I am experimenting with a single chip Universal Active Filter, in this case I made a small PCB for the UAF-42 from Texas Instruments. I chose this part in particular as it facilitates setting ...
