Title: Optical fiber transmission line measuring method
Inventor: MORIMITSU MAMORU
IPC: H04B17/00
Filed: 1997-09-25
Abstract: PROBLEM TO BE SOLVED: To obtain the transmission delay time and distance of an optical fiber transmission line based on only a reference clock at a reception side. SOLUTION: An optical fiber transmission line 17 with a known refractive index at different wavelengths λ1 and λ2 is used. The same light signals with different wavelengths λ1 and λ2 are simultaneously transmitted from a transmission side λ1 to a reception side. Since the transfer speed of the light signal of each wavelength is determined uniquely by the refractive index and a transmission delay time until the light signal of each wavelength arrives differs according to the distance of a light transmission line, a delay time difference Δt is measured by obtaining the difference of the arrival time of each wavelength based on a reference time 112 at the reception side at the reception side 18.  Based on the delay time difference Δt and the refractive index at each wavelength, transmission delay time in the optical fiber and optical fiber transmission distance are calculated only at the reception side.

Title: Secondary beat cancel circuit
Inventor: KIMURA KATSUMI
IPC: H04N9/89
Filed: 1984-12-29
Abstract: PURPOSE:To delete completely a secondary beat component even in a variable speed reproduction mode where dynamic tracking is produced, by securing the coincidence between the delay time of a delay time circuit provided to a non-correlative signal detecting circuit and the horizontal cycle of a reproduction signal. CONSTITUTION:In a variable speed reproduction mode, the horizontal cycle of a reproduction signal varies in response to the tape driving speed. Thus the output of a shaping circuit 122 which is supplied to a PLL110 also varies in response to the tape driving speed. Then the cycle of a clock signal supplied from a voltage control oscillator 113 and phase-locked to the output of the circuit 122 is also changed. Furthermore, the delay time of a variable delay circuit 101 which is driven by the clock signal is also changed in response to the tape driving speed. Thus the complete correlation is secured between luminance signals Y of the input and the output of the circuit 101. Then the secondary beat component CB is extracted completely by a non-correlative signal detecting circuit 100 including the circuit 101. This component CB is cancelled by a secondary beat signal processing means 90 and a subtractor.
