The paper deals with signal analysis in frequency domain oriented on improving its effectiveness. New approach to the problem is proposed. This leads to obtaining better results than the ones being well known from standard techniques based on DFT and FFT transforms. Our method uses adaptive synthesis aided by evolutionary algorithm. Main attention is focused on signal analysis with short duration...
The problem of making precise frequency-domain representation of discrete-time signals, knowledge of which is restricted to a very small number of samples, i.e. is based on the number of samples which are equal to or less then several dozen, is discussed in the paper. The proposed approach utilizes adaptive synthesis aided by evolutionary algorithm. One of the main advantages of the presented method...
