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 ...

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 ...

The circuit was designed with the combination of high pass filter and low pass filter to create a notch filter circuit. High Pass Filter – an electronic circuit that allows the passage of high ...

My previous column described the Sallen-Key circuit for a low-pass filter. At times, you will not find a low-pass filter with the specifications you need in an anti-alias circuit, so you might decide ...

If you are in any way connected with radio, you will have encountered the low pass filter as a means to remove unwanted harmonics from the output of your transmitters. It’s a network of capacitors and ...
