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 ...

Today we are going to explain about one more important concept – “FILTERS”. An electrical filter is a circuit, designed to reject all unwanted frequency components of an electrical signal and allows ...

Bandpass filters are used in both wired and wireless communications systems, sensor applications, instrumentation, medical applications, and many others. When it comes to these types of applications, ...

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 ...

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 ...

Logic Noise is an exploration of building raw synthesizers with CMOS logic chips. This session, we continue to abuse the 4069UB as an amplifier. We’ll turn the simple unity-gain buffer of last session ...
