We found this circuit in a 1969 General Electric documentation. The circuit uses transistors of the time and the diodes in the dotted board must be mounted on the output transistor heatsinks.
This circuit is ideal for the design of interfaces and shields, as it allows total isolation of...
Found in a 1968 EEE, this circuit accepts frequencies from 1 to 1000 Hz and control voltages from 0.1 to...
Found in a 1970 EEE this circuit emulates a zener diode whose voltage can be set to R2. Power...
