Does a finite duration signal have finite effective （RMS） …
Nov 7, 2024 · $\begingroup$ this is, by the way, a very strange definition of bandwidth. I'd say it's not very useful in practice. For example: Signal 1 has a PSD of exactly 1 between -1 Hz and +1Hz, zero everywhere else (any sensible definition would give that signal an bandwidth of 2Hz).
How are time resolution and signal bandwidth related?
Oct 19, 2011 · The closer the enemy signal to be excluded (thus the narrower the bandwidth allowed for your signal), the longer it takes to differentiate friend or foe, which leads to a worse time resolution. If you could tell from one sample, that implies you're accepting an infinite bandwidth, which is just one corner case of the time-bandwidth dual.
What's the theoretical bandwidth? - Signal Processing Stack …
Dec 24, 2019 · This is the closed form frequency response of a DFT bin. This is the bandwidth of a sampled radio signal- so it can be real or complex depending on the way that signal is received. If you have a zero mean signal because you have removed the mean from the signal you sampled would be very different than if you sample a zero mean (noise) signal.
Root mean square bandwidth of a signal with flat spectrum
If this width is the same for a low pass signal and for a band pass signal, then the bandwidth of the band pass signal must be twice the bandwidth of the corresponding low pass signal, because bandwidth is measured at positive frequencies only.
Bandwidth of lowpass filter? - Signal Processing Stack Exchange
Jun 30, 2016 · If we substitute the minimum sampling frequency in the above equation we obtain: $$\frac{F_{signal}}{2 \cdot F_{signal}} = \frac{1}{n}$$ So that means that we obtain the highest frequency when the period of signal is described by 2 samples. This is all the story behide normalized frequency, I hope that this can help you in some way.
Does bandwidth include negative frequencies? - Signal Processing …
Sep 23, 2023 · Single-sided and double-sided bandwidth needs to be specified explicitly to be clear. The double-sided bandwidth of a modulated signal at baseband (including the negative frequencies) corresponds directly to the occupied bandwidth at RF (passband) in either the positive or negative frequencies: for example a baseband signal that extends from -1 MHz to +1 MHz in spectral occupancy when ...
bandwidth - How does Ettus X310 sampling rate work? - Signal …
Nov 4, 2024 · What is the actual signal bandwidth offered by X310? With a 200 MS/s sampling rate, you can represent at most a bandwidth 200 MHz. The actual analog frontend bandwidth is defined by the daugherboard; there's daughterboards with many different bandwidths; the wider ones do 160 MHz, some do 120 MHz, others 80 MHz or 40 MHz.

OFDM transmitter bandwidth - Signal Processing Stack Exchange
The harmonics caused by resampling however cause the bandwidth to increase from 40 to 80 Hz. Question. What should the bandwidth of the BPSK OFDM signal be after resampling? Is it 50 Hz (according to theoretical graph shown), 40 Hz (simulated before resampling) or 80 Hz? Should a filter be used to achieve the correct bandwidth?
