Question

Why flat top sampling is better than natural sampling?

Answer 1

Hey mate.

Here is your answer.

✔For the generation of a PAM signal we use a flat top type PAM scheme because during the transmission,

✔The noise is interfered at top of the transmission pulse which can be easily removed if the PAM pulse in flat top.

✔In natural top scheme this is not possible.

Answer 2

Explanation:

• When an ‘analog signal’ is converted to discrete signal or the analog (or continuous) signal is made to occur at a certain intervals of time the process is termed as sampling.
• 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.
