Felix Strecker

from Wikipedia, the free encyclopedia

Felix Strecker (born February 27, 1892 in Jarotschin district (Dembno); † November 10, 1951 in Munich ) was a German electrical engineer at Siemens .

Life

In 1929, Strecker and Richard Feldtkeller brought the quadrupole theory to a conclusion by introducing the matrix calculation.

In the early 1930s he established the stability criteria for the locus . Similarly, Harry Nyquist established the criterion in 1932, which was later called the stability criterion by Nyquist .

In his review of Marcello Pirani , Strecker highlighted new aspects such as the use of function scales in the graphic evaluation of certain integrals, interpolation in network tables, traveling curves, sliding curves.
