The PicoScope 9404-05 has a built-in full-bandwidth trigger for each channel, with pre-trigger ETS (equivalent-time sampling) capture available to well above the Nyquist sampling
For instance, it is restricted by the Nyquist sampling
limit, the receiver needs a high sampling rate for the wideband waveform, which causes to the large resource consumption for data storage and processing.
The principal ingredients are the differential X-ray scattering cross sections of the elements and the Nyquist sampling
However, a large amount of data will be produced when monitoring the composite structure real-time and online by the use of ultrasonic phased array technology with Nyquist sampling
theorem, which not only needs complicated processing of the data but also needs higher requirements for the acquisition system to complete the data collection.
In order to capture all the information from the continuous signal, it is necessary to fulfill the Nyquist sampling
The core of traditional image coding (e.g., JPEG) is the image transformation based on Nyquist sampling
Thus the following Nyquist sampling
constraint should be met in order to avoid aliasing along the slant range direction:
In recent years, a new theory named compressive sensing (CS)  has surpassed the limits of the Nyquist sampling
We define the time interval of the Nyquist sampling
frequency as T.

theorem is widely accepted as a means of representing band-limited signals by their digital samples.
Traditional approaches to acquiring and sampling signal are based on Nyquist sampling
theory, which states that the sampling rate must be at least twice the maximum frequency of the input signal.
