The sampling interval is defined as the ratio of the population size (N) to the desired sample size (n), determining the distance between units selected in systematic sampling.

Complex sampling (or I/Q sampling) is the simultaneous sampling of two different, but related, waveforms, resulting in pairs of samples that are subsequently treated as complex numbers.

Apr 10, 2025 · From an engineer's viewpoint, the sampling interval is dictated by the Nyquist theorem, which states that the sampling frequency must be at least twice the highest …

Mar 25, 2024 · Definition: The sampling interval is maintained throughout the population list, and the process stops once the end of the population is reached. Example: Selecting every 5th …

If the size of the population or universe is N and n is the size of the sample, then the integer that is at least as large as the number N/n is called the sampling interval (often denoted by k).

Dec 11, 2025 · For example, a 250 m ground traverse with 25 stations along it has a sampling interval of 10 m; a wave-form might be sampled every two milliseconds, i.e. with a sampling …

In research terms, also referred to as ‘nth selection’, this is when we select every nth participant (sampling unit) in the list; this sampling interval produces a random selection from throughout …

Jul 15, 2025 · Systematic sampling is a probability sampling method where samples from a larger population are selected according to a random starting point but with a fixed, periodic interval.
