In the system discussed, six variables are simultaneously adjusted according to some optimising criterion. The self-adjusting computer has been applled to optimisation studies involving up to six variable parameters, process indentification, and the solution of linear and non-linear simultaneous algebraic equations. ~> ELLIS E.J. : An equalizer for an electro-magnetic vibrator system employing analogue computing techniques, ]ourn.

This tnne is ultimately limited by the charging time of the field-effect transistor junction. In typical device suitable for analogue multiplication the charging time is found to be about 10-20 nsec for a multiphcation error of less than one percent.

Specifically treated is the restricted three-body problem, numerous examples of which are presented, as weli as comparisons to digital results Some attendant problems are presented. Limited dynamic range, capacitor dielectric absorption, and electronic multiplier limitations are described in some detail. Automatic scale-changing techmques are detailed, which produce the high accuracy shown, as well as providing near-optimum scaling at all times. ~> (Information Processing Journal, vol. 3, n ° 1-2, p. 36).

The operation of these amplifiers is like that of a self-balancing bridge. Depending on the type of feedback and source impedance (resistive or capacitive), the amplifiers can be made to operate as voltage amplifiers, differentiators, or integrators Using semiconductors and tubes as external active elements, the amplifiers can perform many non-linear functions such as : compression, expans,on, root and power generation; limiting, clipping and logarithmic amplification. >> (Information Processing Journal, vol. 3, n ° 1-2, p. 35). 621 375.4.024 GIRALD G., MARTIN j'.C.
