虽然很多人都知道FFT是什么，可以用来做什么，怎么去做，但是却不知道FFT之后的结果是什意思、如何决定要使用多少点来做FFT。-Although a lot of people know what is the FFT can be used to what to do, how to do, but do not know the results after the FFT is a very mean, how to decide how many points do want to use FFT.

注:protel电路图 1.INPUT12为高压气压和低压压传感器输入端. 2.OUTPUT为充气输出控制端. 3.当高低压有接地信号时,电机正转,气阀打开. 4.INPUT2低气压时有信号时,充气OUTPUT输出,充气电机转. 5.RS1与RS2是调节阀门距离用地 6.RS3是与气阀电机同步时,是气阀电机的转动圈数传感器. 7.RS4是调节延时时间用地-Note: protel circuit 1.INPUT12 and low-voltage high-pressure pneumatic pressure sensor input. 2.OUTPUT output control for the inflated side. 3. When the high and low pressure have a grounding signal when the motor is transferred, the valve opens. 4.INPUT2 low pressure when there is signal output OUTPUT inflatable, inflatable motor switch. 5.RS1 and RS2 is the regulator valve from the land 6.RS3 synchronous motor with the valve, the valve motor is rotating circle the number of sensors. 7.RS4 delay time to regulate land
