1、对给定的一路波形信号，计算该信号的均方根（jfg）的大小。

2、当信号频率f在20HZ~50HZ的时候，采用时间中断没隔1s通过SCI传输该信号的均方根大小给上位机观察和显示；当信号频率f在50HZ~100HZ之间，则没隔0.5s传输1次；当信号频率f在100HZ~1000HZ之间，则没隔0.2s传输一次；当信号频率f超过1000HZ时，停止传输信号。…

-1, the waveform of the signal given way to calculate the signal' s RMS (jfg) in size. 2, when the signal frequency f in 20HZ ~ 50HZ, when not using the time interrupt every 1s SCI transmit the signal by the rms size of the observation to the host computer and display　When the signal frequency f between the 50HZ ~ 100HZ is not separated 0.5s transmission 1　when the signal frequency f between the 100HZ ~ 1000HZ, then no one transmission every 0.2s　when the signal frequency f over 1000HZ, stop the transmission signal. ...
