Testing measurement system with which kind of dynamic input? - ANSWERStep
because it is easy to execute, covers broad range of frequencies, and yields time
constant (time for system to respond)
0th order system - ANSWER"Immediate" response
No storage, no inertia in sensor or system
1st order system - ANSWERSimple delayed response
Measurement system absorbs and stores energy when sensing variable
2nd order system - ANSWERDelayed response with potential oscillation
Measurement system dissipates and stores energy, requires moving and inertial
component
KA - ANSWERSteady response
y(t) - ANSWERTime response
(y(0)-KA)exp(-t/tau) - ANSWERTransient response
Time constant - ANSWERTime for system to reach 63.2% of step change
magnitude, t=tau
Rise time - ANSWERTime for the system to reach 90% of the step change
magnitude
Frequency bandwith - ANSWERFrequency band over which magnitude ratio is
greater than 0.707
