The low-light photographic performance of smartphones could soon get a significant boost, thanks to the development of a new type of color filter. Created by an engineer at the University of Utah, the ...

The low-cost composite passive filter in this Design Idea requires no dc power and can enhance the performance of audio equipment and instrumentation by rejecting power-supply hum and spurious pickup ...

A low-pass filter is the most common filter found in data acquisition systems. Typically this type of filter is used to reduce analog-to-digital converter (ADC) aliasing errors and noise outside the ...

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 ...

Any pointers to good resources on audio filters for WAV files (particularly low-pass filters) implemented in Java? I've found a goodly amount of resources on DSP and filters, but when it gets to ...

Filter modules with built-in transformers offer 10G designers a wealth of design and performance-enhancing options. In June 2006, the IEEE committee ratified the 10GBaseT specification (IEEE 802.3an) ...
