please suggest that which course I have to choose (Sensors and Actuators) or (Probability and random Process) or (complex and lenear algebra) or (science and technology) in my 3rd semester of b-tech.and iam in ECE branch
It will depend on you in what topics you find interest . I suggest you to choose something which you are interested . Each topics are vast and informative in their own domain. In Sensors and Actuators you have to study about various types of sensors like
Vision and Imaging Sensors.
Temperature Sensors.
Radiation Sensors.
Proximity Sensors.
Pressure Sensors. And Actuators like
electric motors, stepper motors, jackscrews etc.
Probability and random process includes
General aspects.
Foundations of probability theory.
Random variables.
Conditional probability.
Theory of probability distributions.
Properties of probability distributions.
Applied probability.
Stochastic processes. Etc
In complex and linear algebra , topics like
Fourier transform
Laplace transform
Bassel theorem etc.
Regarding Science and Technology , topics like
Communication Technology. Emerging Technologies. Health Care Technology. Science, Technology, and Innovation Policy may be present.
Hopes this helps.
Wish you luck!
