|
|
When A accurated measurement of Length and Positioning was carried out with a testing apparatus making use of Moire´ light, it is necessary to use a apparatus of Electronic tube circuit.
In this paper, the Design and Manufacture of one Electronic tube circuit for this purpose has been included.
Electronic circuits are made up of the coarse scale circuit system for wave shaping from coarse scale detector and fine scale circuit system for amplifying signals from fine scale detector.
Included in the coarse scale circuit system are two step cathode follower circuit, three step A.C amplifier circuit, two step rectifier circuit, two step low pass filter circuit, a Differential amplifier circuit, a Differentiating circuit, a monostable multivibrator circuit, and included in the fine scale circuit system are two step cathode follower circuit, two step A.C amplifier circuit, a low pass filter circuit and a cathode input amplifier circuit.
The result of the experiment and analysis showed that low SN ratio and low input voltage get bigger in all coarse, fine scale circuit systems.
