First, all MTF curves reach zero value at spatial frequencies f [less than or equal to] 30 lp/mm--that is, substantially below the calculated

Nyquist frequency (38 lp/mm)--indicating that the photographic resolution is adequate for the presented analysis [22, 23].

It can realize a compensation range of 6-21 dB in the effective frequency band, the DC gain can change from -10 dB to 5dB, and the peaking frequency can scan from 1.25-12.5 GHz (at

Nyquist frequency), which can provide an area-efficient alternative for passive inductive terminations and well satisfy the equalization ability.

The

Nyquist frequency is 10 Hz for the oscillator, At this sample rate, the RMSE is the highest for almost all derivatives.

Secondly, in the scenario of streaming of the CS-compressed signal, we analyzed 4 different compression ratios with respect to the 2 kHz

Nyquist frequency: 2x, 4x, 5.33x, and 8x.

The maximum frequency for THD computation is

Nyquist frequency. The Maximum frequency range is set to 1000.

The LTC2320-16 features a flexible analog front end that accepts fully differential, unipolar, or bipolar analog input signals as well as arbitrary input signals, and it maintains an 82-dB SNR and a high CMRR of 102 dB when sampling input signals up to the

Nyquist frequency. The wide input bandwidth of the LTC2320 allows the digitization of input signals up to the

Nyquist frequency of 750 kHz.

holds, the Nyquist theorem states that the maximum frequency accessible is given by the

Nyquist frequency [f.sub.Ny] = c/(2[DELTA]x).

where x[[n.sub.c]] is sample sequence of original signal [x.sub.s] which meets the

Nyquist frequency and T is sampling period.

Closely related to that is the minimal required sampling frequency (twice the "

Nyquist frequency") 1/[T.sub.s] = [f.sub.s] [greater than or equal to] 2[f.sub.max], which is necessary to obtain all information about the signal.

Two common methods are usually used to prevent aliasing: (1) using a strong analog antialiasing (AAA) filter strategy; although this strategy provides good removal, AAA filters are physically large, expensive, and inherently limited in cutoff capability and phase matching, and (2) oversampling approach, where sampling frequency is much greater than

Nyquist frequency, which has the most of quantizing noise distributed outside the interested frequency.

So, an energy transfer is made from the lower frequency range [B(1 - [alpha]),B] to the higher one [B, B(1 + [alpha])] in order of the odd symmetry of the

Nyquist frequency characteristic.

In addition, the AD7768 offers extensive digital filtering capabilities, such as a wideband, low 0.005 dB pass-band ripple, antialiasing low-pass filter with sharp roll-off, and 105 dB stop band attenuation at the

Nyquist frequency.
