minimitaajuuden
Minimitaajuuden refers to the minimum frequency in Finnish technical usage. It is used to describe the lowest frequency component present in a signal or the lower operating bound of a system. In signal processing, the concept is closely related to the fundamental frequency—the reciprocal of a signal’s period—and to the lowest spectral component of the signal. When a signal has a finite bandwidth, minimitaajuuden marks the lower edge of that bandwidth and helps define what portion of the spectrum is transmitted, measured, or processed.
In practical terms, minimitaajuuden is determined by design choices and physical limits. In electronics and instrumentation,
Measurement and analysis of minimitaajuuden commonly involve spectrum analysis, Fourier transforms, or spectrograms to identify the
