In an electronic engine control (EEC) for a turbine engine, a high rotor speed signal (N2SYNTH) is synthesized from a sensed low rotor speed signal (N1) in a primary control channel (32) so long as the low rotor speed signal is healthy. If the low rotor speed signal (N1) is not healthy, the primary...
