Instantaneous Spectral Analysis (ISA)

by

Astrapi® has introduced a ground-breaking technique for constructing and analyzing signals using sinusoidals with continuously-varying amplitude. Instantaneous Spectral Analysis (ISA) is a sharp break from the existing practice of representing signals as sinusoidals which have constant amplitude over some period of time. With ISA, it is possible to construct signals using only sinusoidals in a … Read more
