STAGGERED INTERLEAVED NYQUIST REGIONS AVOID GUARD BAND INDUCED HOLES WHEN SAMPLING A BAND LIMITED SIGNALStaggered interleaved Nyquist regions associated with differing ADC clock rates (F) avoids spectrum lost through disjoint guard bands at the end of or between adjacent Nyquist regions. The staggered ...
Yao and Thomas have studied the properties of some special functions forming orthonormal set and their Fourier-Transform as required in Sampling expansion of band-limited signal. In this paper we consider the Associated Legendre Polynomials and generalized Prolate Spheroidal wave functions which are band...
This paper proposes an interpolation method called the window function method in which the sampling theorem and the window functions are combined. The cause of the generation of the interpolation error is the folding distortion due to the multiplication of the time-limited window to the input ...

摘要: Band-limited signals form an important class of signals. Many important properties of the band-limited signals are discussed and the sampling theorem for them is proved. Some implications of the sampling theorem are discussed. DOI: 10.1080/09747338.1980.11450372 年份: 1980 收藏...
Filling in a couple of blanks in your question I get to the guess that you're undersampling your band-limited signal at regular intervalls. For that situation you'll have the zoom-fft method. There are 2 contributions on the matlab central file exchange, just search for 'zoom fft'....
By using minimum energy signals, we have already reported a new approximation method for band-limited signals. In the proposed method, sampling points are selected from a given time interval so as to minimize the square error between the original and the approximation signals. However, when this...
1. The input stereo signal is split into lowpass and highpass components using a crossover filter. The filter's crossover frequency is equal to the speaker's cutoff frequency (set to 60 Hz in this example). 2. The highpass component,hpstereo, is split into left and right channels:hple...
