This circuit generates signals whose frequency depends on C1 and C2. JFETs are common types like BF245 or MPF102.
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...
