Study Notes
Logic Circuits
- A combinational logic circuit consists of logic gates whose outputs are determined from only the present combination of inputs.
Sum of Products (SOP) Expression
- A sum of products (SOP) expression is directly implemented by a product-of-sums (POS) logic circuit.
Logic Circuit Implementation
- A combination of two AND gates, one OR gate, and two inverters implements a NAND-NAND logic circuit.
Inverter Implementation
- An inverter is used to implement a NOT logic circuit.
Sequential Logic Circuit
- A sequential logic circuit employs storage elements in addition to logic gates.
