Feedback is the screeching or howling sound caused by feeding the output of an audio system back to the its own input, for example pointing a microphone at the speakers that are the output of the microphone signal. This causes amplification of the already amplified signal in an endless loop resulting in an overload of the audio circuitry.
This is a low-pass filtered used in digital audio equipment.
Passes a band of frequencies between two limits.
Passes frequencies above a threshold frequency.
Passes frequencies below a threshold frequency.
Passes frequencies above and below a chosen band of frequencies. i.e. it cuts frequencies within the chosen bandwidth.

Used to create a ‘flanging’ effect. Flanging is commonly done using an electronic processing device to filter an input signal. This treatment introduces harmonically related notches in the filter response.
Frequency = Wavelength * Time
Basically the amplitude of the modulating signal dictates the amount of deviation from the carrier frequency, and the frequency of the modulating signal dictates the rate at which the deviation occurs.
Metallic strip typically made of nickel-silver. Mounted on the fret board, a fret marks the position on the guitar neck where a guitar string will create a specific pitch, when pressure is applied behind the fret to shorten the guitar string length.
