| 1 | Can change the process of division ratio. | |
| 2 | This is well below the compression driver's crossover point. | |
| 3 | Through spotlights cost reducing and frequency division utilization it improves system efficiency. | |
| 4 | This is the most simple-frequency circuit, only one counter will be. | |
| 5 | The method has been successfully employed in computer simulation for the fractional frequency transmission system. |
