Web31 Oct 2024 · Sub-band coding consists of two phases. In the first phase, analysis, the signal is processed with a set of k k analysis filters, creating k k new signals. These signals are downsampled by a factor of k k by taking every k k th value (thus maintaining the same total amount of data).
