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