The main topics covered include:
Amplifiers: Types of power amplifiers (Class A, Class B, Class AB, Class C), feedback (positive and negative), oscillators (Phase shift, Wien-Bridge), multivibrators (Astable, Monostable), and the Schmitt Trigger circuit.
Number Systems: Decimal and Binary number systems, 1's and 2's complement of binary numbers, and signed binary number representation.
Codes: BCD (Binary Coded Decimal), ASCII, EBCDIC, and Gray Code.
Boolean Algebra: Commutative, Associative, Distributive, Double Negation, Identity, and Redundancy laws, Venn diagrams, and SOP/POS (Sum of Product/Product of Sum) forms.
Logic Gates: De-Morgan's Theorem, Universal logic gates (NAND and NOR), and implementation of various gates using NAND.
Karnaugh Map (K-map): A tool for minimization of Boolean expressions and elimination of potential race hazards.
Combinational Circuits (Logic): Demultiplexer, Comparator, Parity, Multiplexer (MUX), Decoder, and Encoder are mentioned, along with their uses or definitions.
Arithmetic Circuits: Parallel binary adder, Full adder using half adders, and serial adder.
Flip-Flops: Sequential circuits (Edge-triggered and Level-triggered), Latch, RS Flip-flop, JK Flip-flop, D Flip-flop, and T Flip-flop.
Registers & Counters: Register (Buffer and Shift), types of shift registers (SISO, PISO, SIPO, PIPO), Universal shift register, Ring counter, and types of counters (Asynchronous/Ripple and Synchronous).
Logic Families: TTL, ECL, CMOS, RTL, DTL, and characteristics of logic families (Propagation delay, Fan-in, Fan-out, Power Dissipation, Noise Margin).
A/D & D/A Converter: Analog to Digital Converter (ADC) and Digital to Analog Converter (DAC), their types, and associated parameters like resolution and conversion time.
Programmable Logic Devices (PLD): ROM, PLA (Programmable Logic Array), and PLD.
