WebMay 22, 2024 · Time Scaling. This property deals with the effect on the frequency-domain representation of a signal if the time variable is altered. The most important concept to understand for the time scaling property is that signals that are narrow in time will be broad in frequency and vice versa. WebMay 22, 2024 · In this module, we will derive an expansion for any arbitrary continuous-time function, and in doing so, derive the Continuous Time Fourier Transform (CTFT).

WebThe spectra are shifted by the sampling frequency. So if your signal has a frequency that is greater than half of the sampling frequency, then you'll get aliasing. This means that your spectrum will be folded back into the frequency interval $[0,f_s/2]$. $\endgroup$ – small ships star citizenWebQuestion: 2. Numerical Approximation to CT Fourier Transform A large class of signals can be represented using the continuous-time Fourier transform (CTFT) in Eq. (4.1).
