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. WebContinuous-Time And Discrete-Time Signal. This classification is based on the horizontal axis (time axis) of the signal. Continuous and discrete …
