  3. Scope • Covered • Chapter 1 ~ 9, 12 • Not covered • Chapter 10, 11, 13, 14 • Trouble Shooting • System Application Activity • Design with HDLs

  4. Chapter 1 & 2 • Logic Levels (Noise margin, compatibility) • Number systems (bin, octet, hex…) • Conversions • Arithmetic • 1’s and 2’s complements, signed numbers • Codes • BCD, Gray codes

  5. Chapter 3 & 4 • Basic gates (inverter, AND, OR, NAND, NOR, XOR, XNOR), their functions and symbols • Universality of NAND and NOR gates • AND-OR logic • Boolean rules and Axioms • Simplifications • Analysis of combinational circuits • Standard forms • minterms, maxterms, standard SOP, standard POS • K-map • SOP minimization

  6. Chapter 5 & 6 • Analysis of combinational logic • Implementing combinational logic with basic gates • Functions of combinational logic circuits • Adders, comparators, decoders, encoders, code converters, MUX, parity checker • Design Logic with IC • With decoders • With MUX

Chapter 7 Flip-flops • Bi-stable device • Latch (S-R, S’-R’) • Flip-flops • D, J-K • Their symbols • Flip-flops with asynchronous set/reset • Operating characteristics of FF • Setup time, hold time, max clock frequency • Applications of FF • Timers • One-shot • 555 timer (multi-vibrator, one-shots)

  8. Chapter 8 Counters • Asynchronous Counters • Synchronous Counters • Design of counters with FF • Design of counters with IC • Synchronous load • Asynchronous reset

  9. Chapter 9 Shift Registers • Shift register operations • Serial in/Serial out, Serial in/Parallel out, Parallel in/Serial out, Parallel in/Parallel out • Shift Register Counters • Johnson Counter • Ring Counter • Applications of SR • Serial to parallel conversion
