Found in RCA documentation from the 90s, this circuit uses components from that time. CA3019 is uncommon today and can be replaced by discrete diodes.
This circuit is quite simple to assemble, having been found in a traditional American publication. The...
This rectangular oscillator produces signals of two frequencies, one double the other. The circuit is...
This oscillator can generate signals up to about 10 MHz, depending on the crystal used. The...
