Abstract

PURPOSE:To perform various electrical and dynamic measurements by performing electric and dynamic conversion before applying a signal source to an object to be measured, and applying the converted signal to be the object to measured. CONSTITUTION:A device 1 is the signal source of the pseudo noises. Its output signal fo(t) is divided into two signals. One of said output signals is converted into an electrical and dynamic signals by a converter 11 which converts the signal into the electrical dynamic signals suitable for the object to be measured. Said converted signal f(t) is applied to the object to be measured 2, and the response value g(t) from the object to be measured is converted by a Fourier converter 3. The other of said output signals fo(t) is converted by a Fourier converter 4. A device 5 is a computing circuit where the output G(w) from the converter 3 is divided by the output fo(w) from the converter 4. The output H(w) of the computing circuit 5 is a transmission function, and many frequency responses can be obtained from this fuction.
