Time-Correlated Radio-Frequency-Interference Analysis

Cnventional radio-frequency-interference (RFI) receiversmeasure various characteristics of the incident RPI signals contiouily in time with the capability of selecting the freqency range of interest, the system described here extends the capability of commerclly available RFI receivers to selectively measre RFI at time domain as well. The application: of this technique to the measure of RFI due to ndividual cyiders of multicylinder spark ignition engines is described.
