What is flat top sampling and natural sampling?
Flat Top Sampling: Flat top sampling is like natural sampling i.e; practical in nature. In this sampling techniques, the top of the samples remains constant and is equal to the instantaneous value of the message signal x(t) at the start of sampling process. Sample and hold circuit are used in this type of sampling.
Why Is Flat Top sampling preferred?
With the help of hold and sample circuit ‘flat top sampling’ is done. In flat top sampling the top of samples are constant and are equal to instantaneous value of the signal while a more practical method of sampling is natural sampling in which the width of pulse is finite.
What are the following terms mean instantaneous sampling sampling and Flat Top sampling?
Out of these three, instantaneous sampling is called ideal sampling whereas natural sampling and flat-top sampling are called practical sampling methods.
What is top sampling?
TOP stands for “top of production” and is a set of sample that is taken off the line during your first production run. Once you are comfortable with the top of production sample, you give the manufacturer approval to proceed with bulk production.
What is the importance of sampling theorem explain natural and flat top sampling?
Sampling theorem states that in any pulse modulation system if the sampling rate of the samples exceeds twice the maximum signal frequency, then this ensures the reconstruction of the original signal in the receiver with minimum distortion.
What is the disadvantage of Flat Top sampling?
What is the main disadvantage of Flat top sampling? The sampling rate is large in proportion with f. This has practical limitations. The sampled signal spectrum has spectral gaps.
What is the error introduced in Flat Top sampling?
In flat-top sampling, due to the lengthening of the sample, amplitude distortion and delay are introduced. This distortion is referred to as the aperture effect and occurs during the reconstruction of g(t) form s(t).
What is the sampling principle of Flat Top sampling?
Flat Top Sampling During transmission, noise is introduced at top of the transmission pulse which can be easily removed if the pulse is in the form of flat top. Here, the top of the samples are flat i.e. they have constant amplitude. Hence, it is called as flat top sampling or practical sampling.
