In the picture above S marks the duration for sample and hold which indicates that in this time period the input signal will actually captured that is a snapshot if its physical value is taken.
|
|
|
|
After this time it will be converted to a digital value in the conversion phase marked with C.
|
|
|
|
When the conversion had finished this loop may start again. In parallel the result could be used for further processing marked as R.
|
|
|
|
This technique has a natural boundary in terms of how fast it can provide new samples which is the sum of the sample time and the conversion time.
|
|
|
|
Thus limiting the highest frequency of the samples signal according to the sampling theorem of Nyquist-Shannon.
|
|
|
|
To overcome this limitation a different technique of sampling named ETS [comp. [2] p.273ff] can be used although it introduces limitations on the applicability.
|
|
|
|
The principle of ETS is shown in chapter xy of this wiki.
