What are filter banks used for?
A digital filter bank is a set of digital band pass filters that is used to analyze a given input signal by separating it into multiple signals with non-overlapping frequency content. They can also be used to synthesize or construct multiple input signals of non-overlapping frequency content into a single output.
What is a filter bank CNN?
CNN layers can be thought of as filter banks of complexity increasing with the depth. Filter banks are powerful tools to extract texture features and have been widely used in texture analysis. In this paper we develop a simple network architecture named Texture CNN (T-CNN) which explores this observation.
What are mel filter banks?
The Design Mel Filter Bank block outputs a frequency-domain auditory filter bank using the mel frequency scale. You can use a mel filter bank to decompose an audio signal into separate frequency bands in the mel frequency scale, which mimics the nonlinear human perception of sound.
What is a switch filter bank?
Switched Filter Banks consist of a combination of switches and filters integrated into a single module. Integrating filter and switch components in a single module eliminates transitions between circuits, providing for optimal matching.
What is auditory filter bank?
Auditory filter banks are non-uniform bandpass filter banks designed to imitate the frequency resolution of human hearing [308,180,87,208,255]. Classical auditory filter banks include constant-Q filter banks such as the widely used third-octave filter bank.
What is M channel filter bank?
The M-band filter bank is a generalisation the two-channel filter bank in which the incoming signal is split into several components that lie in bands that cover the Nyquist frequency range, which is the interval [0,π], measured in radians.
