Application of Digital Signal Processors based on Methods of Spline-Functions for One-Dimensional Signals Processing

This paper is devoted to the issues of using digital signal processors for processing and smoothing one-dimensional signals and experimental data. The use of cubic basic splines and smoothing splines for approximating signals is proposed. VisualDSP++ simulator was used as a medium for modelling of signal processing processes, as well as development and debugging of programs for digital signal processors. This environment includes an easy-to-use assembler, a C/C++ compiler, and a C/C++ executable function library that includes mathematical and DSP functions. A key feature of the simulator is the effectiveness of code written in C/C++. The results of processing and smoothing of one-dimensional seismic signals and experimental data obtained as a result of magnetic prospecting are also presented.
