What we have learnt

  • Analog signals are continuous, whereas digital signals are discrete and represented in binary form.
  • Boolean algebra is fundamental for computing and involves logical operations and various laws.
  • Combinational and sequential circuits form the basis of all logical operations in digital systems.
  • Microprocessors and microcontrollers serve different purposes in computing and embedded systems.

Key Concepts

-- Analog Signals
Continuous signals that vary over time and can represent physical quantities like audio or temperature.
-- Digital Signals
Discrete signals that represent data as binary values (0 and 1), allowing for precision and noise immunity.
-- Boolean Algebra
A branch of algebra that involves binary variables and logical operations, essential for digital circuit design.
-- Logic Gates
The building blocks of digital circuits that implement Boolean functions: AND, OR, NOT, NAND, and NOR.
-- Karnaugh Map (KMap)
A visual method for simplifying Boolean expressions to minimize the number of gates required in a circuit.
-- FlipFlops
Bistable devices that store a single bit of data, serving as the fundamental building block for sequential circuits.
-- Microprocessor
A computer processor that integrates the functions of a CPU on a single chip, used primarily for general-purpose computing.
-- Microcontroller
A compact integrated circuit designed to govern a specific operation in an embedded system.
