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.
Found in a 1968 US publication, this circuit is designed to measure very weak signals. The...
The sensor can be made using two bare wire or two screen with a piece of tisse between them. One...
This circuit serves as a binary demonstrator using 3 LEDs. The circuit can be scaled up for a...
