A SIMPLIFICATION OF THE SOUND VELOCITY METER FOR FIBRES

DENG LI-RHU ,
HU SHIH-RHU

Received Date: 17 June 1964

The circuit for the excitation of longitudinal vibration of a fibre which was described in a previous paper is simplified. A multivibrator circuit triggered by line voltage is used so that the pulse generator is not necessary.
