tippväärtus

Tippväärtus is a term used in Estonian technical language to denote the peak value or the highest magnitude reached by a signal, function, or dataset under specified conditions. It describes the value at the peak of a curve or waveform and is often used in engineering, physics, and data analysis.

In mathematics and data analysis, tippeväärtus can refer to the maximum or the supremum of a function on its domain. For a continuous function, it is the highest y-value attained; for discrete data, it is the largest observed data point. The concept is related to, but distinct from, local maxima and global maxima depending on the context and domain.

In signal processing and electronics, tippeväärtus commonly means the peak value or peak amplitude of a time-varying signal, usually denoted as Vpk for voltage or Ipk for current. For alternating quantities, the peak-to-peak value (Vpp) is related to the peak value by Vpp = 2 · Vpk for a symmetric waveform. The peak value is a different metric from the root-mean-square (RMS) value, which measures effective power.

In statistics, the term is sometimes used informally to indicate the highest observed value, but standard terminology prefers maksimum for the overall maximum and local maksimum for a peak within a subset of the domain. The usage of Tippväärtus can vary by field, so precision often requires specifying whether a peak is local, global, or simply the observed maximum.

Etymology and usage notes: Tippväärtus is a lexical construction in Estonian technical language; in formal writing, more explicit terms such as maksimum, lokal maksimum, or Vpk are typically preferred.
