Directing the spectrogram data to the synthesizer unit with the appropriate deemphasis of the amplitude frequency response, we will be able to verify that the speech signal(with the exception of the phase-frequency relationship) is restored, and the required intelligibility is completely ensured.
Apparently disorganized polymorphous oscillations of 1-20 Hz were observed on ECG-record at seconds 176-180 but spectrogram showed domination of low and middle frequency oscillations(4-12 Hz) over the frequency range between 1 and 40 Hz Figure 1(g).

They developed a shell for linked hierarchic vocabulary databases, in which phonetic files with actualsounds(taken from expeditionary materials) as well as spectrograms made in Praat program can easily be added, which improves phonetic analysis capacity.
This measurement creates a spectrogram of the pulse, which can be used to determine the complex electric field as a function of time or frequency as long as the nonlinearity of the medium is known.
For completeness and ease of reference,the 2-20 Hz frequency range could be shown on a common time axis alongside the 20Hz-15kHz logarithmic spectrograms, but should be segregated and rendered separately with an independent colour scale so as not to restrict the dynamic range of the>20 Hz data.
Spectrograms may be created from a time-domain signal in one of two ways: approximated as a filterbank that results from a series of band-pass filters(this was the only way before the advent of modern digital signal processing), or calculated from the time signal using the Fourier transform.
The state of the autonomic nervous system tone was evaluated traditionally by the ratio of the high-frequency heart rates in the spectrogram to the low-frequency rates( LF/ HF)[ 7, 8], and also by the ratio of the number of the self-organization processes of the heart rate regulation system involving parasympathetic nervous system to the number of the same processes involving sympathetic nervous system, i. e.
