We found this circuit in a 1965 Electronic Design. Transistors are still common but admit equivalents for some of them. The circuit drains a current of only 4 mA.
The purpose of the circuit shown in the figure, obtained from a 1972 documentation, is to delay the...
This circuit is from a 1968 publication. Here we have several types of resistive sensors with...
