Implication

This research derives expressions for quantization noise in sigma-delta modulation, aiding converter design.

Key Points

  • The aim is to understand how the sampling rate affects quantization noise in sigma-delta modulation systems.
  • Derived algebraic expressions for quantization noise and its spectrum based on input amplitude.
  • Validated results using measurements from a breadboard circuit.
  • Quantization noise is highly correlated with input amplitude.
  • Derived theoretical expressions match experimental results, indicating their reliability.
