Binary search, a decrease-and-conquer approach, plays an important role in testing today�s low-pass filters. When testing a low-pass filter, generally you have to use an arbitrary waveform generator ...

In most video systems, low pass filters are included on the video output lines of the video encoders. These filters reject the high frequency noise and smooth out the rise/fall edges of the video ...

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 ...

Imperfect Amplifiers, Parasitic Capacitance, And Component Selection All Impact Filter Performance At High Frequencies. Since professors R.P. Sallen and E.L. Key described it in 1955, the Sallen-Key ...

A scheme of simple band-pass RC- and LR- filters on operational amplifiers containing only one capacitor or inductor and 3 resistors is proposed. A comparison is made of the amplitude-frequency ...

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 ...

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 ...

A filter that blocks high frequencies and allows lower frequencies to pass through. Such filters are used in devices such as POTS splitters that direct phone and DSL signals to different lines.
