The invention relates to a system for predicting high frequency emission information of an engine is provided. The system comprises a control device being configured to receive low frequency emission information from an emission measurement device, said emission measurement device having a first sampling frequency equal to or below a first predetermined sampling threshold configured to the output low frequency emission information having the first sampling frequency. The control device is further configured to execute a model. Said model, when executed by the control device, predicts high frequency emission information as a function of the low frequency emission information and at least one predetermined high frequency engine input parameter, the predicted high frequency emission information having at least a second sampling frequency above the first predetermined sampling threshold. The invention further relates to a corresponding prediction method and a training method.
