For baseband signal, the sampling is straight forward. By Nyquist Shannon sampling theorem, for faithful reproduction of a continuous signal in discrete domain, one has to sample the signal at a ratefsfshigher than at-least twice the maximum frequencyfmfmcontained in the signal (actually, it is ...
The fundamental result in Sampling Theory, known as Shannon's Sampling Theorem, has many applications to signal processing and communications engineering. We will demonstrate Shannon's result via complex interpolation methods. We then quote a result of Casey which uses these methods to solve ...

The Shannon-Nyquist Sampling Theorem In the following, we simulate the sample theory on an anolog signal:y=0.5sin(2πf1t)+2sin(2πf2t)y=0.5sin(2πf1t)+2sin(2πf2t), whose frequece isf1=15f1=15andf2=40f2=40. We selectfs=3fmax=3×40=120Hzfs=3fmax=3×40=120Hz. We...
The sampling rate is large in proportion with f2. This has practical limitations. The sampled signal spectrum has spectral gaps.To overcome this, the band pass theorem states that the input signal x(t) can be converted into its samples and can be recovered back without distortion when ...
When the uniform sampling without replacement is applied in the ensemble Nyström method, we can get the error bounds as follows. Theorem 7 Error Bounds for the Ensemble Nyström Method with Uniform Sampling [16] Let S be a sample of pℓ′ columns drawn uniformly at random without repla...
The Nyquist frequency is discussed in the next paragraph. 2.2 Nyquist theorem and antialiasing low-pass filter relaxation The Nyquist theorem states that to reconstruct the analog input signal, the signal must be sampled at a rate Fs (sampling frequency...
