In general, a digital system designer has better control of tolerances...
Explanation: Analog signal processing operations cannot be done very precisely either, since electronic components in analog systems have tolerances and they introduce noise during their operation. In general, a digital system designer has better control of tolerances in a digital signal processing system than an analog system designer who is designing an equivalent analog system.

Control of Tolerances in Digital vs. Analog Systems
In digital signal processing, designers enjoy greater control over tolerances compared to their analog counterparts. Here’s why:
1. Discrete Levels
- Digital systems operate with discrete values (0s and 1s), which simplifies the design process.
- Each bit represents a specific state, allowing for robust error detection and correction methods.
2. Noise Immunity
- Digital signals are generally more resistant to noise and distortion.
- Small variations in signal levels do not significantly affect the system's performance, as long as the signal remains above a certain threshold.
3. Component Variability
- In analog systems, component tolerances (resistors, capacitors, etc.) can lead to significant variations in performance.
- Digital components can be designed to operate within tighter tolerances, minimizing variability due to manufacturing imperfections.
4. Reproducibility
- Digital systems can be easily replicated and scaled without loss of performance.
- Analog systems may require tailored adjustments for each unit to ensure consistent performance, complicating the design process.
5. Design Tools and Techniques
- Advanced design tools for digital systems allow for simulation and optimization of designs, facilitating better control over tolerances.
- Techniques such as feedback and digital filtering can further enhance performance consistency.
In summary, the inherent characteristics of digital systems—discrete levels, noise immunity, reduced component variability, reproducibility, and advanced design tools—grant digital designers superior control over tolerances compared to analog system designers.
