系统内冗余或重复数据的度量,表明存储和潜在性能问题效率低下。
1 SR = 2 RD
1 RD = 0.5 SR
例子:
将15 信号冗余转换为冗余数据:
15 SR = 30 RD
| 信号冗余 | 冗余数据 |
|---|---|
| 0.01 SR | 0.02 RD |
| 0.1 SR | 0.2 RD |
| 1 SR | 2 RD |
| 2 SR | 4 RD |
| 3 SR | 6 RD |
| 5 SR | 10 RD |
| 10 SR | 20 RD |
| 20 SR | 40 RD |
| 30 SR | 60 RD |
| 40 SR | 80 RD |
| 50 SR | 100 RD |
| 60 SR | 120 RD |
| 70 SR | 140 RD |
| 80 SR | 160 RD |
| 90 SR | 180 RD |
| 100 SR | 200 RD |
| 250 SR | 500 RD |
| 500 SR | 1,000 RD |
| 750 SR | 1,500 RD |
| 1000 SR | 2,000 RD |
| 10000 SR | 20,000 RD |
| 100000 SR | 200,000 RD |
