Summary

This slide set provides a compact, accessible introduction to fundamental digital signal processing concepts, covering sampling, discrete-time signals, LTI systems, and basic digital filters. Readers will also get a practical overview of FFT-based spectral analysis and examples focused on audio and speech processing.

Key Takeaways

• Apply the sampling theorem to assess aliasing and determine anti-alias filter requirements.
• Design and evaluate basic FIR and IIR filters using windowing and bilinear-transform approaches.
• Compute and interpret FFTs and spectrograms to analyze audio/speech signals in the frequency domain.
• Implement core DSP operations (convolution, z-transform reasoning, frequency response analysis) for practical signal-processing tasks.

Who Should Read This

Undergraduate students, junior engineers, or practicing engineers new to DSP who want a concise, slide-based overview of foundational DSP concepts and practical audio/speech examples.
