WebApr 30, 2024 · In signal processing, there is a time-frequency duality. Band-limited signals have infinite time duration and time-limited signals have infinite bandwidth. Where … WebAug 8, 2024 · Why does every single band-limited signal in frequency have an infinite time domain and vice versa (As it's a symmetric relation, inf in one is finite in the other). I understand how a digital signal with an infinite slope needs infinite amount of sine waves to approximate or achieve, hence it being infinite in the frequency domain.

WebMathematically, a signal can never be truly band-limited. A law of Fourier transformations says that if a signal is finite in time, its spectrum extends to infinite frequency, and if its bandwidth is finite, its duration is infinite in time. Clearly we cannot have a time-domain signal of infinite duration, so we can never have a truly band ... Web3.3 Band-limited signals. One important class of signals is the class of band-limited signals. These signals are characterized by the fact that their Fourier transform is zero outside a range of frequencies; that is, \(x(t)\) is said to be band-limited if there exists a number positive number \(f_0\) such that \( X(f) = 0\) for \( f > f_0\).We discuss this with …
