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 ...

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 ...

At one time or another, most electrical engineers encounter a requirement to design or analyze an analog filter. Despite an abundance of graphical-user-interface-based digital-filter-design tools, ...

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, ...

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 ...
