WebApr 7, 2024 · 1.1 Fourier transform. In our mind a (1D) signal is nothing but a time series. This means that we have an x axis, which is the time, and a y axis, which is the quantity we are considering (e.g. voltage). From an intuitive point of view, doing a Fourier transform of a signal means to see this signal in another domain. WebAug 12, 2013 · The dynamic time warping seems suitable for adjustment of derived genomic signals. DTW originally serves for processing of digital signals sampled at defined time instances. In genomic signals, time instances are represented by indexes of nucleotides. The signals based on cumulated phase carry not only useful information, but also noise. incoterms r 2010
