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. ...
