Modular codes are widely used in many areas of modern information technologies. The use of these non-positional codes can provide high-speed data processing. Therefore, these algebraic systems should be used in the algorithms of digital processing of signals, which are characterized by processing large amounts of data in real time. In addition, modular codes make it possible to implement large-scale signal processing using the wavelet transform. The paper discusses examples of the Daubechies wavelet transform application. Integer processing, presented in the paper, will reduce the number of rounding errors when processing the speech signals.en2079-929220187Art.-Nr. 120MDPIhttps://creativecommons.org/licenses/by/4.0/modular codeslarge-scale signal processingwavelet transform Daubechiesbasic functions of DaubechiesPhysikTechnikJournal Articleurn:nbn:de:gbv:830-882.04471410.15480/882.234810.3390/electronics707012010.15480/882.2348Other
