Numeral Systems • Base-2 numeral system • Represents numeric values using two symbols • Decimal System: Base-10 numeral system - 10 Symbols • 200 – 2 Symbols • 1256 – 4 Symbols • Values and Symbols – Communicating the Value through Symbols
Binary Digital Systems • Base-2 numeral system is being used here 0101101100111 • A voltage level in a point in the circuit represents the symbol corresponding to a value.
Layered Model • Ex. Filling a water tank with 2 pipes. Inflow 1 Inflow 2 System Layer Numeral Layer Physical Layer
Transistor • The Quantifier • The Switch • The AD Converter
Other Digital Systems • Ternary Digital Systems • What are the available components
