There is disclosed a well fluid sampling tool (5) and related well fluid sampling method.

The sampling rate of the A/D converters (103a-103b) is controlled by a sampling clock signal (104) generated by a timing recovery circuit (107).

A sampling circuit receives a divided clock signal and produces a digitized signal.

The time relationship of the system and sampling clocks is controllable.

A sampling method and apparatus for sampling a dither signal (22) includes the step of sensing a number of peak amplitudes P1, P2, P3...

A flyback power supply (10) which includes a sample and hold feedback path.

Sampling errors, on the other hand, can be evaluated statistically.

An apparatus and a method for feeding a sample into a sample channel (20) are disclosed, the apparatus having a source for a carrier fluid.

(v) It should be unaffected by sampling fluctuations

By comparing the energy values either one of these signal sampling time points (n = 8, n = 9) can be selected as the sampling time point for the symbol sequence.

With I = period of sampling (multiple of 1 minute)

Pedagogical Simulation of Sampling Distributions and the Central Limit Theorem

For consecutive sequences, an average value for the sampling time points is calculated.

The gas analyzer has a sample cell (11) for containing a gas mixture to be analyzed.

One rate of the sampling clock is a function of a timing signal (160) applied to the timing recovery circuit (107).
