How this entity was disambiguated
This entity first appeared as the object of triple T13601946 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

-
A.
Cooley–Tukey Fast Fourier Transform algorithm
The Cooley–Tukey Fast Fourier Transform algorithm is a widely used, efficient method for computing the discrete Fourier transform that revolutionized digital signal processing and numerical analysis.
-
B.
Daubechies wavelets
Daubechies wavelets are a family of compactly supported orthogonal wavelets widely used in signal processing and image compression for their efficient time-frequency localization.
-
C.
Haar wavelet
The Haar wavelet is the simplest and oldest wavelet function, used as a basic building block in wavelet analysis for representing signals with abrupt changes.
-
D.
Subband Codec
Subband Codec (SBC) is an audio compression format commonly used over Bluetooth for efficiently transmitting medium-quality stereo sound with relatively low computational complexity.
-
E.
Perceptual Quantizer
Perceptual Quantizer is a high-dynamic-range (HDR) electro-optical transfer function designed to closely match human visual perception of brightness for modern video and display systems.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
