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.
The circuit shown in the figure is suggested by Texas Instruments and allows data transmission on TTL devices...
We find this vibrato configuration with transistors in a 1987 documentation. The components are still...
This circuit, from a documentation from the 1970s, produces two sinusoidal signals given by C2 and...
