- The sinusoidal response is a common response type in first-order industrial process control systems. This response is characterized by the oscillation that occurs in the controlled variable around its steady state value, when a sinusoidal input is applied to the system. Which of the following correctly describes one of the main characteristics of the sinusoidal response in first-order systems?
a) The amplitude of the sinusoidal response is not affected by the frequency of the sinusoidal input.
b) The amplitude of the sinusoidal response increases as the frequency of the sinusoidal input increases.
c) The amplitude of the sinusoidal response decreases as the frequency of the sinusoidal input increases.
d) The phase of the sinusoidal response is directly proportional to the frequency of the sinusoidal input.
e )The phase of the sinusoidal response is inversely proportional to the frequency of the sinusoidal input.
- Relevant Equations
- G(s) = K/(Ts + 1) (basic first orde transfer function)
This a homeawork from my graduate course. I know that a sinusoidal input affects both the amplitude and phase of the response, but I don't know how it does.
I'd be really glad if someone could help.
Thanks
