We show in the figure how to implement the No-AND or NAND logic function using a general-purpose transistor. The 47 k base resistors and collector can be changed to other supply voltages.
We found this circuit in a documentation from the 90s. It is a simple test for NPN and PNP...
Suggested by General Electric in a 1967 publication, this circuit uses the D13T1, an uncommon SCR...
This 80's Exar circuit has a carrier detector for frequencies up to 500 kHz. The circuit uses a...
