THE SYNCHRONOUS MAGNETIC RECORDER AND ITS APPLICATIONS--II: EXPERIMENTAL.

G SURYAN

Abstract


The design considerations regarding the construction of a synchronous magnetic recorder for the extraction of weak signals in noise and the description of an actual devise are given. Striking photographs giving the input and output signals illustrate the practicability of the basic ideas. The signal to noise ratio in the output of the recorder has been discussed and rough criteria and methods for judging the same are given.
