Many sensors have a small analog signal that rides on top of a larger dc pedestal. For these circuits (Fig. 1), the signal must be ac coupled and amplified before it’s digitized. The feedback of an ...

Try looking up Fast Fourier Transforms. That will convert your signal to an array of frequency magnitudes, you can attenuate the lower frequencies, and then reverse-FFT back to the filter signal.

Seoul National University College of Engineering announced that a research team led by Prof. Sung-Hoon Ahn of the Department ...

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 ...

As a follow-up to my previous blog, Integration Choices: Analog Filters vs. Digital Filters, the next step would be to discuss how to integrate filters into the IC itself. What techniques and ...

The circuit was designed to create a classic electronic crossover circuit that will provide a 3-way output on all loudspeakers. Electronic Crossover – an external electronic signal processor that ...
