All-pass filter
An all-pass filter is a signal processing filter that passes all frequencies equally, but changes the phase relationship between various frequencies.

Band rejection
Band rejection is a phenomenon in waveform signals, where a certain frequency or range of frequencies are lost or removed from a source signal.

Band-pass filter
A band-pass filter is a device that passes frequencies within a certain range and rejects (attenuates) frequencies outside that range.

Band-stop filter
In signal processing, a band-stop filter or band-rejection filter is a filter that passes most frequencies unaltered, but attenuates those in a specific range to very low levels.

Bandwidth (signal processing)
Bandwidth is the difference between the upper and lower frequencies in a contiguous set of frequencies.

Bode plot
A Bode plot is a graph of the transfer function of a linear, time-invariant system versus frequency, plotted with a log-frequency axis, to show the system's frequency response.

Sinc filter
In signal processing, a sinc filter is an idealized filter that removes all frequency components above a given bandwidth, leaves the low frequencies alone, and has linear phase.

Transition band
The transition band is a range of frequencies, that allows a transition between a passband and a stopband of a signal processing filter.
