Sampling Rate Conversion
Hylmar, Petr ; Vítek, Martin (referee) ; Kozumplík, Jiří (advisor)
This thesis is focused on sampling rate conversion by a rational factor interpolation and decimation and sampling rate coversion by an arbitrary factor interpolation and decimation. There are described methods sampling rate conversion in time domain based on lowpass FIR linear filter and in spectral domain based on zero spectral lines. These methods are created in Matlab programming and tested on particular example. The results of this thesis are sensible parameter lowpass FIR linear filter for sampling rate conversion and discussion success rate used methods.

Sampling Rate Conversion
Chrobák, Martin ; Provazník, Ivo (referee) ; Kozumplík, Jiří (advisor)
This bachelor’s thesis is engaged in design of procedure for change of sampling rate of EKG signal using 3 methods: with positive integer factor D/I, with any factor (I=8) and with any factor (I=16). Sampling rate conversion should be realized from 500 to 360 Hz and from 360 to 500 Hz in time and frequency part of signal. For this, it is used a professional computing interface of MATLAB, which is perfect for processing of signals. The output from this work should be recommendation which filters (with how long impulse characteristics) are useful for this change of sampling rate.
