AN-236An Introduction to the Sampling Theorem

The sampling theorem by C E Shannon in 1949 places restrictions on the frequency content of the time function signal f(t) and can be simply stated as follows: — In order to recover the signal function f(t) exactly it is necessary to sample f(t) at a rate greater

Searches related to sampling theorem pdf filetype:pdf

Sampling is recording values of a function at certain times Allows for transformation of a continuous time function to a discrete time function This is obtained by multiplication of f(t) by a unit impulse train Impulse Response Train Consider an impulse train: Sometimes referred to as comb function

How to express sampling theorem?

Sampling theorem can be expressed as given below: Sampling is a process of translating continuous analog signal into discrete analog signal, where the sampled signal is the discrete time representation of the original analog signal.

What is the shannonsampling theorem?

Frequently this is called the Shannonsampling theorem, or the Nyquist sampling theorem, after the authors of 1940s papers on the topic. The sampling theorem indicates that a continuous signal can be properly sampled, only if it does not contain frequency components above one-half of the sampling rate.

What is sampling theory?

Sampling theory is the bridge between the continuous-time and discrete-time worlds. The information inherent in a sampled continuous-time signal is equivalent to that of a discrete-time signal. A sampled continuous-time signal is a sequence of impulses, while a discrete-time signal presents the same information as a sequence of numbers.

Which electronic filter is used to comply with the sampling theorem?

FIGURE 3-7 Analog electronic filters used to comply with the sampling theorem. The electronic filter placed before an ADC is called an antialias filter. It is used to remove frequency components above one-half of the sampling rate that would alias during the sampling. The electronic filter placed after a DAC is called a reconstruction filter.
