What will happen if we sample a signal with under sampling condition?
When undersampling a real-world signal, the sampling circuit must be fast enough to capture the highest signal frequency of interest. If the sampling theorem is interpreted as requiring twice the highest frequency, then the required sampling rate would be assumed to be greater than the Nyquist rate 216 MHz.
Why signals should be limited to sample?
For baseband signals, the bandwidth and hence the sampling frequency depend solely on the highest frequency present. For bandpass signals, bandwidth is usually smaller than the highest frequency. Thus, band-limited signals can be sampled and fully recovered only when observing the Nyquist criterion.
What is the relationship between sampling and signal fidelity?
The higher the sampling rate the higher the fidelity and the higher the storage requirements. Digital sound sampled at high fidelity rates requires massive storage.
Which is the sampling frequency for band pass signal?
The sampling frequency for band pass signal which is having frequency from 4 kHz to 6 kHz(rectangular shape from 4 to 6 kHz), can I prefer the sampling frequency of 12 kHz(2*the highest frequency p… Stack Exchange Network
What happens when you sample a continuous time signal?
Sampling a continuous-time signal that contains higher frequencies than half the sampling frequency will result in aliasing: Samples of those high frequencies are identical to and cannot be discerned from samples of other frequencies below half the sampling frequency.
Which is band limited for a discrete time signal?
A discrete-time signal represents a continuous-time signal that is band-limited to at most half the sampling frequency.
What is the difference between sampling and downsampling?
Terminology: sampling – creating a discrete signal from a continuous process. downsampling (decimation) – subsampling a discrete signal upsampling – introducing zeros between samples to create a longer signal aliasing – when sampling or downsampling, two signals have same sampled representation but differ between sample locations.
