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 = 1 FDR
1 FDR = 1 SR
例子:
将15 信号冗余转换为频级冗余:
15 SR = 15 FDR
| 信号冗余 | 频级冗余 |
|---|---|
| 0.01 SR | 0.01 FDR |
| 0.1 SR | 0.1 FDR |
| 1 SR | 1 FDR |
| 2 SR | 2 FDR |
| 3 SR | 3 FDR |
| 5 SR | 5 FDR |
| 10 SR | 10 FDR |
| 20 SR | 20 FDR |
| 30 SR | 30 FDR |
| 40 SR | 40 FDR |
| 50 SR | 50 FDR |
| 60 SR | 60 FDR |
| 70 SR | 70 FDR |
| 80 SR | 80 FDR |
| 90 SR | 90 FDR |
| 100 SR | 100 FDR |
| 250 SR | 250 FDR |
| 500 SR | 500 FDR |
| 750 SR | 750 FDR |
| 1000 SR | 1,000 FDR |
| 10000 SR | 10,000 FDR |
| 100000 SR | 100,000 FDR |
