Yes, human voice is not single-frequency (if it was, it would sound like a sinusoidal tone). Strictly speaking, any finite-duration signal does have infinite bandwidth. But, most energy in human …

May 12, 2021 · Another example is analog television: the signal is designed to have a bandwidth of 6 MHz, and except for equipment malfunction, you'll never find a TV signal with frequencies …

8 I'm new to signal processing. I'm plotting a signal in the time-domain in matlab. I don't understand which parts of the signal are high frequencies and low frequencies, can someone …

If you sample a bandlimited signal in time at higher rate, you get a more 'squashed' spectrum, i.e. a spectrum with more zeros at both ends. In other words, you can obtain more samples in time …

Apr 16, 2020 · Suppose we sample a continuous time signal with sampling period Ts = 1/2000, and then use a window of length 1000 on the resulting discrete time signal. If we transform it …

The formula for the alias frequency is the absolute difference of the signal frequency and the closest integer multiple of the sampling frequency - can someone explain this to me? Thanks …

Computing the power at a single frequency means that you assume that the signal has a sinusoidal component at that frequency. For a continuous frequency spectrum (without …

11 When the signal is modulated onto the carrier in the electromagnetic spectrum, that signal occupies the small portion of the spectrum surrounding the carrier frequency. It also cause …

Feb 23, 2022 · Shannon-Nyquist theorem states that signal has to be sampled at least twice the maximal frequency. If you sample your signal with frequency of 100Hz, as i like to think of it, …
