Controls and instrumentation - SYNCHRONIZING AND SYNCHROPHASING

want to read about :  Controls and instrumentation Electronic indicating systems

SYNCHRONIZING AND SYNCHROPHASING
58. Synchronizing and synchrophasing systems are  sometimes used on turbo-propeller engined aircraft to achieve a reduction of noise during flight.
59. On a multi-engined aircraft, a synchronizing system ensures the propeller speeds are all the same. This is achieved by an electrical system that compares  speed  signals  from  engine-mounted generators.  Out-of-balance  signals,  using  one engine  as  a  master  signal,  are  automatically corrected by electrically trimming the engine speeds until all signals are equal.
