oscillograph's Usage Examples:

(London, 1901), which contains a list of original papers on the oscillograph; Id.

Blondel, and are exemplified by his oscillograph and that of W.

Blondel, " Oscillographs: New Apparatus for registering Electrical Oscillations " (a short description of the bifilar and soft iron oscillographs), Comptes rendus (1893), 116.

des Sciences (1898), for a paper on oscillographs describing Blondel's original invention of the oscillograph in 1891.

A form of thermal oscillograph has been devised by J.

In this case the large vibrating mirror must be oscillated by a current from an alternator, on the shaft of which is a disk of nonconducting material with brass slips let into it and so arranged with contact brushes that in each period of the alternator a contact is made, charging say a condenser and discharging it through the oscillograph.

, The Principles of Electric Wave Telegraphy (London, 1906), which gives illustrations of the use of the oscillograph and the Braun cathode ray tube in depicting condenser discharges; also, for the development of the oscillograph, A.

In the Duddell oscillograph it is usual to place a pair of loops in the magnetic field, each with its own mirror, so that a pair of curves can be delineated at the same time, and if there is any difference in phase between them, it will be detected.

In one form of Blondel's oscillograph, the vibrating system is a small magnetic needle carrying a mirror, but the principle on which it operates is the same as that of the instrument above described.

The oscillographs of A.

The oscillograph can be made to exhibit optically the form of the current curve in non-cyclical phenomena, such as the discharge of a condenser.
