FADEC and EEC are completely interchangeable terms depending on the engine manufacturer.
The FADEC (single channel) controlled engines on the RJ have the "resolvers" on the engine with a mechanical linkage from the levers.
The EEC (which is the control part of the FADEC) on the PG1500 are resolved at the thrust levers.
There isn't even a standard definition of FADEC
Full Authority Digital Electronic Control on one engine and Full Authority Digital Engine Control on another.
Best not to speak in absolutes.
