Description
  • Článek se zabývá spektrální analýzou signálů pomocí DFT. Pozornost je věnována zejména rozlišení blízkých frekvenčních složek a vlivu délky okénka i vzorkovací periody signálu. Těžiště spočívá ve zkoumání tvarů a délek jednotlivých oken a jejich aplikaci na jednoduché signály. Nejlepší výsledky byly dosaženy pro Blackmanovo okénko. Poté byly výsledky aplikovány na reálná data s cílem vyhledat potenciální periodicity. Data obsahovala spotřebu plynu v intervalu 1 rok s periodou vzorkování 1 den. Data byla zpracovávána v týdenní časové jednotce. (cs)
  • The paper deals with the real signal spectral analysis by the mean of DTF. The special attention is given to the differentiation of close frequency compounds and also to the signification both of the window shape and length for the signal real part sampling. The main part of the paper consists in the windows analysis and their application using the convolution character for the given discrete transformation. The various window shapes and various window lengths N were studied applying simple sequences. The Blackman's windows seem to be the best ones comparing the results. Then the real data were used to find the potential periodicity in them. This data file contains the one year summary of the gas consumption with the sampling period 1 day. The data was executed with the basic time unit 1 week because of better orientation. The Blackman window was used for the computation because of the results above.
