In this laboratory course, we will be using the COMDYNA, GP-6 Analog computers that are available in the Systems Engineering Department. The GP-6 is a general purpose analog computer. It contains linear and .nonlinear components. The linear part contains panels for summers, integrators, inverters and attenuators; while the nonlinear part contains multipliers, square-root generators and other components. The GP-6 has a linear range of +10 to -10 volts shown as +1 to -1 unit on the display panel.
