The cap in question is part of the guitar’s tone circuit, which along with a potentiometer forms a variable low-pass filter. A rich folklore has developed over the years around these circuits ...

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

Signals with frequency above or below the filter’s passband will be attenuated. The band-pass itself is constructed from a high pass and a low pass filter. [Ryan] used simple resistor capacitor ...

But by applying the High Pass Filter in Photoshop CC ... so the ability to apply it sparingly in low-light shots is invaluable. Another plus of sharpening in an indestructive manner on layer ...

Since many amateur transmissions are lower in frequency than TV and FM signals, a high-pass filter can be fitted to the receiver to prevent the low frequency amateur signals from reaching it and ...

While the 2045 filter has just a single low-pass mode, the R-8 can be run in low-pass, band-pass, high-pass and notch configurations. When the two filters are combined you get three additional ...

A filter which attenuates frequencies above its cutoff frequency (which is the point where the signal is 3 dB down). The slope of the filter is the rate of attenuation, i.e. 6, 12 or 24 dB per octave.
