Applies the hybrid-pi model to calculate voltage gain, input, and output impedance. Connects DC bias analysis to AC performance prediction.

Lesson 2 • BJT Amplifier Biasing and DC Operating Point

Establishes stable Q-point design using voltage-divider bias networks. Correct biasing prevents distortion and is prerequisite to small-signal analysis.

Lesson 3 • Operational Amplifier Fundamentals

Introduces ideal op-amp properties and the virtual-ground concept for feedback analysis. Op-amp circuits form the basis of signal processing covered in this and later chapters.

Lesson 4 • Amplifier Frequency Response and Stability

Analyses gain-bandwidth product, dominant poles, and feedback stability margins. Prepares students to design stable amplifiers with controlled bandwidth.

Lesson 2 • Boolean Algebra and Logic Gates

Introduces Boolean theorems, De Morgan's laws, and standard gate implementations. Boolean simplification reduces hardware complexity in combinational designs.

Lesson 3 • Sequential Logic and Flip-Flops

Introduces SR, D, JK, and T flip-flops as memory elements for sequential circuits. Flip-flop behaviour is the building block for counters and registers.

Lesson 4 • Number Systems and Binary Arithmetic

Covers binary, octal, hexadecimal, and BCD representations and arithmetic operations. Provides the numerical foundation for all digital logic and microcontroller chapters.

Lesson 1 • Serial Communication Protocols

Introduces UART, SPI, and I2C protocols for microcontroller peripheral communication. Serial interfaces connect microcontrollers to sensors, displays, and other devices.

Lesson 2 • Analog-to-Digital and Digital-to-Analog Conversion

Covers ADC resolution, sampling rate, reference voltage, and DAC output techniques. Bridges analogue sensor signals to digital processing in embedded systems.

Lesson 3 • Microcontroller Architecture Overview

Describes CPU core, memory types, clock system, and bus architecture of a typical microcontroller. Connects digital logic concepts to programmable hardware implementation.

Lesson 4 • GPIO and Digital I/O Programming

Covers pin configuration, input/output modes, and pull-up/pull-down resistors for GPIO control. GPIO is the simplest peripheral and the entry point for all hardware interaction.

Lesson 1 • Power Supply Testing and Protection

Covers output voltage accuracy, ripple measurement, and overcurrent and overvoltage protection circuits. Validates supply performance and ensures safe operation in end-use equipment.

Lesson 2 • Linear Voltage Regulators

Covers Zener shunt regulators and three-terminal IC linear regulators for low-noise DC outputs. Linear regulators provide simple, low-ripple regulation for sensitive analogue circuits.

Lesson 3 • Feedback Control and Regulation Loop

Explains error amplifier, voltage reference, and compensation network in a closed-loop supply. Stable feedback ensures tight output regulation under load and line variations.

Lesson 4 • Switching Regulator Topologies

Introduces buck, boost, and buck-boost converter operation and duty-cycle control. Switching regulators achieve higher efficiency than linear regulators for power-critical designs.
