2. What are the design steps for a microcontroller based electromechanical system? 3. Given that sampling frequency (fs) is equal to 250Hz and Nyquist frequency (fN) is equal to two times of the alias frequency, find the alias frequency. 4. You need to design a quantizer for a sensor which measures voltage values between 40 V and 200 V. If your resolution is 4 (n value) find the number of output states (N) and quantization step (Q).
1. What are the control methods for electromechanical systems. What are
the advantages of each method?

electromechanical system?
3. Given that sampling frequency (fs) is equal to 250Hz and Nyquist
frequency (fN) is equal to two times of the alias frequency, find the alias
frequency.
4. You need to design a quantizer for a sensor which measures voltage
values between 40 V and 200 V. If your resolution is 4 (n value) find
the number of output states (N) and quantization step (Q).
5. Design a capacitive transducer to be able to measure the displacement
of a rotating element in a machine. Sketch the diagram and specify
which parameters will let you measure the displacement.
