ANALOG COMPUTING TRAINER

Item	:	Analog computing trainer
Model	:	CMM-ACT

The Analog Computing board provides an effective educational tool for studying and demonstrating analog computing techniques. The board consist of operational amplifier circuits such as auxiliary circuit, Integrator circuit, differentiator circuit, summing circuit. The circuit is configure in such way so that many configurations can be constructed easily to create models for solving differential equations including 1^st order and 2^nd order equations, linear equation systems and to simulate physical system and transfer functions.

A clear diagram of the components and circuits is printed on top of the board for easy reference and to make the design and analyzing process simpler and quicker. Connections are done by 2mm stackable connecting leads.

A comprehensive manual is provided for teaching and contains step-by-step instruction procedure to do the experiments
