According to our present understanding, the electromagnetic field itself is produced by photons, which in turn result from a local gauge symmetry and the laws of quantum field theory (see the Second quantization and Gauge boson sections below).
Additionally, the frequency conversion performed by applying the DCT provides a statistical decorrelation function to efficiently concentrate the signal into fewer high-amplitude values prior to applying quantization (see below).
A digital filter will introduce noise to a signal during analog low pass filtering, analog to digital conversion, digital to analog conversion and may introduce digital noise due to quantization.
After production spec was set at 16 bits, quantization noise became less of a concern, but emphasis remained an option through standards revisions.
Applications Vector quantization is used for lossy data compression, lossy data correction, pattern recognition, density estimation and clustering.
A more-complete derivation of black body radiation would yield a fully continuous and 'wave-like' electromagnetic field with no quantization.
