French Equivalent: Amplitude

In relation to a time series, the amplitude of a fluctuation is the value of the ordinate at its peak or trough taken from some mean value or trend line. Sometimes the difference between values at peak and trough is referred to as an “amplitude”.

The distance from peak-to-trough in the business cycle. In general, the larger the amplitude is, the more volatile the business cycle will be.
