说明： 在本系统中，信息序列在先经过FSK调制，经过截止频率为25kHz的低通滤波器后（把信号频率限制在25kHz），再进入混频器搬移到更高的频率发送出去，在接收端，用与发送端同步的跳频信号对其进行变频（跳频的解跳处理在此进行），取下边频，然后进行FSK的解调(In this system, the message sequence prior through FSK modulation, through the cut-off frequency of 25kHz after low-pass filter (to limit the frequency 25kHz), and then move into the mixer to a higher frequency to send out, at the receiving end used with frequency hopping synchronization signal transmitter carried on their conversion (FH' s solution to deal with this for jumping), take down side frequencies, then the demodulation of FSK)

buckPWM
There are three kinds of switching mode DC-DC converters, buck, boost and buck-boost. The buck mode is used to reduce output voltage, whilst the boost mode can increase the output voltage. In the buck-boost mode, the output voltage can be maintained either higher or lower than the source but in the opposite polarity.

报童问题(负指数分布)
几个参数：
卖出报纸挣a元，退回报纸赔b元
卖报量y,订报量z，订报量上限z_up
观察期的总天数t,用于积累天数的ti
总的平均损失量ave_loss，供过于求损失loss1,供小于求损失loss2,ave_loss=loss1+loss2
最佳订报量superz,最小损失量ave_loss_min (newsvender)
