Logical diagrams
Logical elements, valves, circuit designer, from simple elements to complex digital blocks.
How do simple elements -- transistors, logic valves -- build a calculator? In this chapter, you will learn how the NMOS transistor works as a key, build an inverter, a semi-summer and a multiplier, master RS- and D-triggers, collect a 2-bit counter and a full counter. Then get to know the AND, OR, NOT, NAND, NOOR, XOR, understand why the NAND is universal, and collect your own scheme in the Drag-and-drop designer.
