MAE 488 - Quiz 1EXAM Questions AND Correct Answers
additive property - ✔✔the property of a system where the output in response to the sum of two inputs
is the sum of the outputs from the individual inputs
Amplitude - ✔✔A in 𝑓(𝑡) = 𝐴𝑒^(±𝑡/tau)
Amplitude - ✔✔A in 𝑓(𝑡) = 𝐴sin( 𝜔t + 𝜙)
causal element - ✔✔an element where the current output does not depend on future input
controller - ✔✔a system that when connected to another system with undesirable properties is
designed to produce desired properties in the combined system
decaying oscillatory motion - ✔✔damped sinusoid
dynamic element - ✔✔an element where the current output depends ONLY on past and current input
Exponential function - ✔✔results in a straight line when plotted on semi-log axes with the dependent
variable on the logarithmic axis (𝑦(𝑥) = 𝑏𝑒^(𝑚x))
Frequency radians/sec (𝜔 = 2𝜋/T rad/s) - ✔✔𝜔 in 𝑓(𝑡) = 𝐴sin( 𝜔t + 𝜙)
homogeneous property - ✔✔property of a system where the output in response to a scalar times the
input is the scalar times the output in response to the nominal input
input - ✔✔an external cause
input-output relationship - ✔✔a description of how the input affects the output (usually called the
mathematical model or just model)
