Continuous-Time Signals and Systems
2-3 weeksStudy continuous-time signal classification, LTI systems, convolution, and the Laplace transform. Understand frequency response, Bode plots, and analog filter design.
Fourier Analysis
2-3 weeksMaster the Fourier series, continuous Fourier transform, and their properties. Learn to move between time and frequency domains and interpret spectral representations.
Sampling, Reconstruction, and Quantization
1-2 weeksLearn the Nyquist-Shannon sampling theorem, aliasing, anti-aliasing filters, reconstruction via interpolation, and the quantization process in analog-to-digital conversion.
Discrete-Time Signals and the Z-Transform
2-3 weeksStudy discrete-time sequences, the z-transform, difference equations, and system stability. Learn to analyze and design digital systems using pole-zero analysis.
DFT, FFT, and Spectral Analysis
2-3 weeksUnderstand the Discrete Fourier Transform, the Cooley-Tukey FFT algorithm, windowing, spectral leakage, and practical frequency-domain analysis of real signals.
Digital Filter Design
2-3 weeksDesign FIR and IIR digital filters using techniques such as windowed-sinc, frequency sampling, bilinear transformation, and Parks-McClellan optimization. Evaluate trade-offs in phase, stability, and computational cost.
Advanced and Applied Topics
3-4 weeksExplore adaptive filtering (LMS, RLS), multirate signal processing, wavelet transforms, statistical signal processing, and applications in audio, image processing, and communications.
