The four-layer diode was the key to William Shockley's plan to revolutionize AT&T's phone system. It was a great device in theory, but not in practice -- at least not at the time when Shockley wanted ...

The circuit above is a 3−input Diode−Transistor Logic (DTL) gate. Write the truth table for the input combinations of 0 V and 5 V with respect to the ground. Which type of logic gate does this circuit ...

Before the era of large-scale integration (LSI) semiconductor circuits, discrete logic circuits using the common diode-transistor logic (DTL) were still necessary and available in a format that was ...
