Accuracy vs Digital Precision Simulator

Understanding accuracy (bias from target) and digital precision (bit resolution) in measurement systems

🎯 Accuracy Control

Accuracy measures how close your measurements are to the true target value (systematic bias).

Level: 75%

💻 Digital Precision Control

Digital Precision is determined by the number of bits used to represent values.

6 bits = 64 levels
Resolution: 1.59 units per level

Current Digital Resolution

Scale divided into 64 discrete levels
Each level represents 1.59 units on the 0-100 scale

📊 Statistical Analysis

🎯 Understanding Accuracy

High Accuracy: Measurements center around the true target value

Low Accuracy: Measurements are systematically biased away from the target

Accuracy is about correctness - how close to the truth

💻 Understanding Digital Precision

Higher Bits: More discrete levels = finer resolution

Lower Bits: Fewer discrete levels = coarser quantization

Digital systems can only represent discrete values, not continuous ones

  • 4 bits = 16 levels (6.67 units/level)
  • 6 bits = 64 levels (1.59 units/level)
  • 8 bits = 256 levels (0.39 units/level)
  • 10 bits = 1024 levels (0.10 units/level)
  • 12 bits = 4096 levels (0.02 units/level)
