6 Apr 1973 The following sampling theorem is proved: Let f(t) be a bounded band- limited function, possibly a sample of a A rigorous proof of this "strong bias tone" scheme is embodied in the implicit sampling theorem to be where the series still converges uniformly in all bounded domains that exclude the poles.
sampling theory while working for Bell Labs, and was highly respected by Claude Shannon, impulse response when dealing with the time domain. rate (which is the rate of audio data) and other sample rates (such as the sample rate of an AD converter input stage or an over sampling DA's output stage).

Objective: To learn and prove the sampling theorem and understand its impli- signal processing, it is important to spend some more time examining issues of sampling. In this chapter we will look at sampling both in the time domain and the frequency domain. We have already encountered the sampling theorem and,
Sampling and. Aliasing. With this chapter we move the focus from signal modeling and analysis, to converting signals back and forth between the analog. (continuous-time) and digital (discrete-time) domains. Back in. Chapter 2 the The lowpass sampling theorem states that we must sample at a rate, , at least twice that of
Sampling and Quantization. Often the domain and the range of an original signal x(t) are modeled as contin- uous. That is, the time damental issues are (i) How are the discrete-time samples obtained from the continuous-time signal?; (ii) How can we .. proof of the sampling theorem. Rather than give a precise proof and
The maximum frequency component of g(t) is fm. To recover the signal g(t) exactly from its samples it has to be sampled at a rate fs ? 2fm. • The minimum required sampling rate fs = 2fm is called.

Sampling Theorem. We will interpret the Sampling Theorem as an orthonormal expansion of bandlimited waveforms. The main reason for discussing the Sampling Theorem is to make concrete the notion that a . Finally, we note that there is almost complete symmetry between time-domain and frequency-domain functions
Sampling: A continuous time signal can be processed by processing its samples through a discrete time system. For reconstructing the continuous time signal from its discrete time samples without any error, the signal should be sampled at a sufficient rate that is determined by the sampling theorem. Nyquist Sampling

An arbitrary narrow-band signal s(t) with the limited spectrum enclosed in the frequency band ± ?fs /2 is fully specified by its frequency values taken with intervals. ?F? = ?fs /? and time values ?Т? = 1/?F? at any integer ? = 1,. 2,
