Abstract
PURPOSE: To facilitate the analysis of frequency variation by only measuring variation in the fine amplitude generated by each fine frequency through correction of varying components of the central frequency relatively slow among all of the frequency variations.
CONSTITUTION: The frequency signal fed to the input terminal 1 is introduced into an input processing circuit 2, converted into a gate signal at each cycle Ti and transmitted to gate circuit 5 and 6. On the other hand, after formed into a timing signal for controlling the computation periods of respective circuits 7 to 10, it is transmitted to the circuits. A correction computer 10 produces the signal indicating the regulation of the input frequency. In addition, an anlaog output is provided through a D-A converter 11.
