Vibration period of the trend term is larger than the length of the sampling frequency of the signal components, generally due to some reason, the test system in the time series generated by a linear trend in error or slowly varying

Trend is larger than the sampling length frequency of the vibration cycle, usually due to test system for some reason the time series generated by a linear or slowly varying trends in errors

The tendency item vibrates the period ratio signal sampling length big frequency component, is generally because test system certain reasons produce in the time series linear or changes slowly tendency error
