FIELD: measurement technology. SUBSTANCE: When digitizing and quantizing a signal under study, K sequences of digitized values of the signal are generated. Each sequence has its own sampling rate. The digitized values are passed through digital bandpass filters and digital low-pass filters. Signals from the bandpass filter outputs are treated to determine information parameters of the bandpass signals. EFFECT: extended functional capabilities of the method due to localization of discrete components of spectra and measurement of their parameters; higher accuracy in measuring parameters of signal spectrum continuous component. |
