Digital Signal Processing is the cornerstone of modern technology, essential for anyone looking to excel in Telecommunications, Audio/Video Engineering, Biomedical Signal Analysis, or Embedded Systems.
While Signals and Systems provides the theoretical foundation, DSP focuses on the algorithmic manipulation of discrete-time signals. In a typical DSP chain, an analog signal is digitized via Sampling and Quantization, processed through sophisticated mathematical operations, and often reconstructed for real-world application.
My teaching approach covers the full spectrum of DSP, ensuring a deep understanding of:
– Discrete-Time Systems: Linear Time-Invariant (LTI) systems, Difference Equations, and Impulse Response.
– The Z-Transform: Stability analysis, Region of Convergence (ROC), and Pole-Zero mapping.
– Frequency Analysis: * Discrete-Time Fourier Transform (DTFT)
– Discrete Fourier Transform (DFT) and the Fast Fourier Transform (FFT) algorithm.
– Filter Design: * FIR (Finite Impulse Response) filters and windowing techniques.
– IIR (Infinite Impulse Response) filters and Butterworth/Chebyshev approximations.
– Stochastic Signal Processing: Random signals, Autocorrelation, and Power Spectral Density (PSD).
– Multirate DSP: Decimation, Interpolation, and Filter Banks.
Since 2015, I have specialized in simplifying the complex mathematical abstractions of DSP. Having mentored over 40 students through rigorous university-level courses, I focus on bridging the gap between abstract theory and practical implementation.
