ATI T-18 Exam UPDATED QUESTIONS AND
CORRECT ANSWERS
Resolver - CORRECT ANSWER A rotary electromechanical device that performs
trigonometric computations electrically
Resolvers - CORRECT ANSWER Can seperate a vector quantity into two right angle
componenets, sine and cosine for resolution. Can combine vectors to produce the sum of the
2 original vectors.
Resolver - CORRECT ANSWER An analog electromagnetic transducer that can be
used in a wide variety of position and velocity feedback applications, due to its simple
transformer design and lack of any on board electronics
Resolver - CORRECT ANSWER Also considered a rotary electrical transformer used
for measuring degrees of rotation
Brushless transmitter - CORRECT ANSWER The most common type of resolver
Stator - CORRECT ANSWER The part of a resolver that delivers the absolute angle
position
50-60 & 400 - CORRECT ANSWER Resolvers designed for terrestrial use tend to be
driven at ____-____ Hz (utility frequency) while those for marine or aviation use tend to
operate at _____ Hz.
A resolver consists of - CORRECT ANSWER A cylindrical rotor with each of the two
phases of rotor and stator in space quadrature
90 degrees - CORRECT ANSWER The resolver rotor constructed of two windings
electrically isolated from each other and displaced by _____.
, Resolution - CORRECT ANSWER Resolvers can separate a vector quantity into its
two right angle components, the sine and cosine.
Resolution (polar-to-rectangular conversion) - CORRECT ANSWER Input signals are
applied to the stator winding and the outputs are taken from the rotor windings
Composition (rectangular-to-polar conversion) - CORRECT ANSWER Resolvers can
combine two right angle components to produce a vector
Voltage gradient - CORRECT ANSWER In resolver electrical parameters the term
sensitivity is also called:
Phase shift - CORRECT ANSWER Another resolver electrical parameter is determined
in the rotor first angular position in EZ corresponding to the maximum coupling and it's
called __________ ___________
CRT (Cathode Ray Tube) - CORRECT ANSWER Converts electronic signals to visual
displays such as pictures, RADAR sweeps, and waveforms.
Electron Gun, Deflection system, and screen - CORRECT ANSWER All CRTs contain
three main elements:
Thermionic emission - CORRECT ANSWER Electrons are boiled off the cathode by:
The purpose of the deflection system - CORRECT ANSWER To bend or deflect the
electron beam inside the cathode day tube (CRT) to illuminate or "paint" lines, symbols, and
any other desired image on the CRT screen.
Attract - CORRECT ANSWER A positively charged electrostatic deflection plate will
_________ the electron beam
