New Technology Breakthrough down-type divider invention <br> audition Technology Co., Ltd. Electronics Engineers from Zhejiang Harman Ye Jianfeng invention "down-type divider series" won the national patents, patent No. ZL 200820121572.5.
In the conventional parallel type divider and series type frequency divider, each frequency division unit is divided into a full-band signal. The working principle of the frequency-down frequency divider invented by Ye Jianfeng is that the full-frequency signal passes through the first frequency division first, and then the high-frequency signal is directly filtered out after the high-pitched signal; and when the middle and low-frequency are divided, the first frequency-divided point is The high-frequency low-pass signal has been filtered out and then the middle and low-frequency crossovers are performed, and the effect is obviously higher than the frequency division from the full-frequency signal. By analogy, the more the number of crossovers, especially the bass effect is more obvious! The effect is also obvious. In other words, once the frequency is divided, the frequency band is lowered once.
For example, a fruit plate consisting of a variety of fruits such as candy, melon seeds, and peanuts (full-range signal). The working mode of the down-converter is divided once, and one is picked out, and the rest is left. Pick. Now, regardless of the parallel and series crossovers, the division of each unit is selected from the full-range signal. It is like three people analyzing and selecting what they need. Everyone is selected from all the fruits. Too many models, picking trouble. Obviously, if you choose one of the two selected ones from the selected one, it is much easier to pick from the three.
Technology has broken through the invention of new frequency-down frequency divider
