The integrated circuits used in this project are uncommon today. It is worth the idea for a microcontrolled project or with equivalents. We found this configuration in an old documentation.
Found in 1968 Mullard documentation, this circuit uses period components. The transistors are...
In the figure we have a modified multiplier circuit that can operate with the sextuplicator with...
This circuit converts signals from the 350 to 500 kHz band to the 4.36 to 4.5 MHz band, enabling...
