It explores Fourier series and transforms, sampling and reconstruction, and system analysis using Laplace and Z-transforms. Advanced topics include filter design, FFT, and matched filtering. Appendices review linear algebra, Hilbert spaces, and analysis fundamentals, with support for interactive content.
