Concept of spectrum-signal transformation
نویسندگان
چکیده
So far, there have been introduced many front-end studies, but most of them fail to present, in a consistent way, how the signals are transformed throughout the front-end itself. In this paper, it is intended to introduce a unique presentation of spectrum and signal transformation within RF front-ends. This approach should help researches to have better insight into the high-level modeling and characterization of RF front-ends and accordingly lead to new design strategies.

متن کاملDepth estimation of gravity anomalies by S-transform of analytic signal
The S-transform has widely been used in the analysis of non-stationary time series. A simple method to obtain depth estimates of gravity field sources is introduced in this study. We have developed a new method based on the spectral characteristics of downward continuation to estimate depth of structures. This calculation procedure is based on replacement of the Fourier transform with the S-Tra...
