Explain the concept of discrete-time system modeling and its application in digital control systems and signal processing.

Choose the correct statements. Select one or more: a. Specific energy expressed with SI base units is J/K. Ob. Dynamic model of a measurement element with second order system dynamics can be expressed with block diagram using only scalar multiplication blocks. c. Feedback can make stable system unstable. Od. A Pl-controller is a controller with four parameters (proportional gain, integration time, derivate time and derivate filter). e. Second order system is a system that's step response oscillates when it have (underdamped) complex valued poles. Of. A thermocouple is one example of non-linear type of sensors. Og. Drift and non-linearity are wanted properties for sensors. Oh. Measurement uncertainty is only caused by external sources. Oi. A Bode diagram is a graphical representation of frequency response that consist of two separate plots (one for magnitude and other one for phase). Oj. A filter is one example of functionality that can be part of signal processing element.

Frequency Response Discuss the importance of Nyquist plot technique in control systems.

Discuss the importance of analog-to-digital converters (ADCs) in microcontroller applications. Provide examples of analog sensors commonly interfaced with microcontrollers.
