theorem is widely accepted as a means of representing band-limited signals by their digital samples.
However, in wireless network, including satellite network, current analog-to-digital hardware technology faces tremendous challenge posed by conventional spectral estimation method which operates in a way equal to or greater than the Nyquist sampling
where P is the device power, ENOB = effective number of bits, and B is the signal bandwidth (hence 2B is the Nyquist sampling
As we have seen in the above analysis, the minimal sample rate of the signal x(t) is 2L/[tau], which is usually much lower than Nyquist sampling
s] must be greater than or equal to the Nyquist sampling
rate fS to avoid loss of information in the sampled signal, where the Nyquist sampling
rate is equal to twice that of the highest frequency component, [f.
The Outputs of SNYFR, Under-sampling and Nyquist Sampling
Because a DDS device works with sampled data, designers must take into account the Nyquist sampling
According to nyquist sampling
criteria, the maximum value of low pass output frequency, [F.
One way to determine the optimum telescope focal length for a given camera is to use the Nyquist sampling
1 have resulted in a new confocal algorithm better tuned to images where proper Nyquist sampling
or over-sampling is used.
The recently introduced theory of compressed sensing (CS) [9, 10] is a new concept allowing the recovery of sparse signal that have been sampled below the traditional Nyquist sampling
