In the figure we have a circuit of an analog computer published in the Radio Electronics magazine of June 1958. Accuracy depends on the components used, mainly the potentiometers.
We find this circuit in the 80's own component manual itself. The characteristics of the circuit...
We found this amplifier with high input impedance and low capacitance, using FET, in a...
This circuit was obtained in a 1979 magazine, but it can be easily assembled today, as the...
