Due to the formal approach to the task of interpolation in the digital signal processing (DSP) statement, existing software implementations of methods for the discrete-time signals (DST) sample rate increase might work incorrectly. In the paper, we have researched features of the method for generation of the DTS with the sample rate increased by integer number of times. We have analyzed results of the DTS reconstruction by means of the MATLAB function interp.m. We have shown that the DTS with an increased sample rate might not satisfy the interpolation task requirements, thus, may vary comparing to results of the DTS reconstruction by means of other classic interpolation methods. |
