Sampling

SAMPLING FOR MINERAL PROCESSING. The golden rule states that for correct sampling all parts of the material being sampled must have an equal probability of being collected and becoming part of the final Therefore for a representative sample The total stream should be sampled The sample cutter should intersect the sample at right angles to the flow.

Sampling (signal processing)

In signal processing, sampling is the reduction of a continuous-time signal to a discrete-time signal.A common example is the conversion of a sound wave (a continuous signal) to a sequence of samples (a discrete-time signal).. A sample is a value or set of values at a point in time and/or space.. A sampler is a subsystem or operation that extracts samples from a continuous signal.
