Abstract :
IN MANY applications the commutator noise produced by conventional tachometers presents great problems. This is particularly true in cases where it is desirable to measure speed variations which have the same frequency components as the commutator noise. It is also true in some servomechanism systems where the commutator noise will saturate the amplifiers or will introduce a spurious response.
