We found this circuit in a 1967 IEEE documentation. The circuit uses discrete components of the time based on the 1.13 MHz frequency used with oscilloscopes at the time.
Found in a Radio Electronics from the 90s, this circuit generates a 1 kHz signal to serve as a...
This low noise circuit was obtained from a 1980s US RF publication. Transistors used are uncommon...
