WebBroad, as well as narrow, band Hilbert transform filters (HTFs) were used as preprocessing units in the analysis of electroencephalogram (EEG) and respiratory movements in neonates. WebDec 17, 2011 · 2. Complex signals, analytic signals and Hilbert transformers. A real signal is a one-dimensional variation of real values over time. A complex signal is a two-dimensional signal whose value at some instant in time can be specified by a single complex number. The variation of the two parts of the complex numbers, namely the real part and the …
