The U1240A Series lets engineers and technicians measure over broad ranges and perform a variety of checks faster with built-in capabilities such as data logging, harmonic ratio
and a switch counter.
On the other hand, the proportional systems of Renaissance architecture seem at times not unrelated to the multiplication chains proposed here; an example is the way Alberti split up compound proportions i nto the smallest harmonic ratios
This experiment investigated the harmonic ratios
of human voices that could potentially improve voice synthesis technology.
