This transistor gain test was published in Radio Electronics magazine in July 1959. The transformer used is a special type common at the time. The circuit tests general-purpose transistors.
This excellent bench source is based on the LM338 integrated circuit, which must be mounted on a...
This shield circuit uses a common CMOS port. The voltage depends on the interfaced logic. The...
This application, shown in the figure, is nothing more than a practical circuit to prove a 4093...
