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.
In the figure we have a simple signal tracer circuit to be coupled to the volume control of an AM...
This circuit was found in documentation from the 90s, using components from that time. The...
This circuit, obtained from old documentation, allows the recovery of sulfated batteries. The...
