2. Signal Representation and Sampling

• Continuous-time signals are represented by functions s(t). For digital systems, analog sources (voice, sensors) are sampled and quantized.
• Nyquist sampling theorem: a bandlimited signal with maximum frequency B Hz can be perfectly reconstructed from samples taken at fs ≥ 2B.
• Quantization: uniform and non-uniform (µ-law, A-law) companding; quantization error modeled as additive noise with variance ≈ Δ^2/12 for uniform quantization step Δ.
