WebSep 22, 2024 · The exact frequency depends heavily on the signal strength and the filter shape of the scope (many scopes do not have a stated filter shape in the documentation!). Now let's go back to the sampling theorem. If we have a band-limited signal with bandwidth B, we'll need to sample it with sampling frequency of 2*B, in order to avoid …

WebSignal design for band-limited channels – ideal channel (9.2-1) Recall: x(t) = transmit pulse * channel * receive filter The overall impulse response of the system is then raised-cosine. For the ideal channel: where GT(f) and GR(f) are the transmit pulse spectrum and the receive filter spectrum. If the receiver filter is matched to the 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 ...
