Advantages of digital techniques: “Greater accuracy and precision are possible with digital techniques.” Evaluate this statement in the context of measurement, storage, and processing.

Introduction / Context:Digital methods have transformed measurement and computation by enabling repeatable calibration, error detection/correction, and robust storage. The claim addresses whether digital approaches generally allow higher accuracy and precision compared with purely analog methods under practical constraints.

Given Data / Assumptions:

• Digital systems use quantization and binary encoding to represent values.
• High-resolution ADCs/DACs and stable references are available.
• Error-correcting codes, averaging, and calibration routines can be applied.

Concept / Approach:While quantization imposes step size limits, digital techniques excel through calibration, filtering, and redundancy. Precision improves with higher resolution (more bits) and oversampling; accuracy benefits from stable references and digital correction. Digital storage avoids drift inherent in some analog storage media, and digital computation is exact with respect to its representation.

Step-by-Step Solution:

Verification / Alternative check:Metrology instruments specify ENOB, linearity, and calibration procedures; digital post-processing compensates errors that are hard to address in purely analog chains.

Why Other Options Are Wrong:

• Incorrect: Ignores advances in resolution and correction.
• Only for low resolution / zero noise: Digital advantages persist across resolutions and realistic noise levels.
• Cannot be judged: General engineering practice supports the claim with measurable specs.

Common Pitfalls:Assuming quantization always reduces performance; in many systems, dithering and oversampling improve effective precision beyond naive expectations.

Final Answer:Correct
