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 ARQ = 1 DF
1 DF = 1 ARQ
例子:
将15 自动重复请求转换为数据保真度冗余:
15 ARQ = 15 DF
| 自动重复请求 | 数据保真度冗余 |
|---|---|
| 0.01 ARQ | 0.01 DF |
| 0.1 ARQ | 0.1 DF |
| 1 ARQ | 1 DF |
| 2 ARQ | 2 DF |
| 3 ARQ | 3 DF |
| 5 ARQ | 5 DF |
| 10 ARQ | 10 DF |
| 20 ARQ | 20 DF |
| 30 ARQ | 30 DF |
| 40 ARQ | 40 DF |
| 50 ARQ | 50 DF |
| 60 ARQ | 60 DF |
| 70 ARQ | 70 DF |
| 80 ARQ | 80 DF |
| 90 ARQ | 90 DF |
| 100 ARQ | 100 DF |
| 250 ARQ | 250 DF |
| 500 ARQ | 500 DF |
| 750 ARQ | 750 DF |
| 1000 ARQ | 1,000 DF |
| 10000 ARQ | 10,000 DF |
| 100000 ARQ | 100,000 DF |
