If a Sigma-Delta converter operates at an oversampling ratio of 64, what would be the apparent resolution improvement in contrast to a standard A/D converter operating at the Nyquist rate? How does this translate to enhanced SNR?
💡 Hint: Consider the logarithmic relationship between sampling rates and resolution.
Propose a scenario where a Sigma-Delta A/D converter would be preferred over a straight binary converter. Justify your choice in terms of resolution and noise management.
💡 Hint: Think of environments that require high precision and noise reduction.
