| Unit | Core Topics Covered | | :--- | :--- | | | Partial Differential Equations (PDEs) : Formation, standard types of first-order PDEs, and higher-order linear PDEs with constant coefficients. This unit builds the foundation for modeling physical phenomena. | | Unit II | Fourier Series : Dirichlet's conditions, half-range series (sine and cosine), complex form, and Parseval's Identity. This series is essential for breaking down complex waveforms and signals. | | Unit III | Boundary Value Problems : Solving the one-dimensional wave and heat equations, which are fundamental to understanding vibrations and heat transfer in engineering. | | Unit IV | Fourier Transforms : Fourier integral theorem, transform pairs (sine, cosine), and properties. This unit expands on Fourier series for non-periodic functions. | | Unit V | Z-Transforms and Difference Equations : Definition, properties, inverse transforms, and using Z-transforms to solve difference equations critical to digital signal processing and control systems. |
: Essential for students focusing on discrete-time systems and digital signal processing.

Solving the two-dimensional Laplace equation in Cartesian and polar coordinates. 4. Fourier Transforms This series is essential for breaking down complex
This is the heart of M3. You’ll learn how to form PDEs by eliminating arbitrary constants and functions, and more importantly, how to solve them using Lagrange’s linear equation and higher-order homogeneous equations. 2. Fourier Series
