Abstract :
A problem for optimal observation of oscillatory motion of a string is considered. It is assumed that the signal could be recorded only from some segments of the string, which are characterized by functions of L2[0,λ] class. By means of some prehistory of the recorded signal, a universal optimal function is constructed, which allows us to determine the deflection and velocity which occurs at any point of the string at any moment of time
