Research and Correction of Distortions when Changing the Sampling Frequency in the Range of Transmitted Levels

The problem of changes in the sound broadcast signal when changing the sampling frequency has become more acute with an increase in the quality of the formation and transmission of the sound broadcast signal. Algorithms for changing the sampling frequency ensured ideal quality when converting a test sinusoidal signal and large errors when converting a real signal. Conversion distortions depend on the signal level, which is not always taken into account when assessing them. The purpose of this work is to study distortions in sampling frequency conversion over the entire range of transmitted levels and use developed algorithms for level compression and changing the sampling frequency to reduce these distortions. It is shown that using the developed algorithms it is possible to reduce the distortions of existing and developed algorithms
