Sample Question 1

Topic: Signal Denoising and Filtering using MATLAB

Question
A postgraduate student is tasked with analyzing a noisy ECG signal and identifying a suitable method to remove noise without distorting the key signal components. The task requires developing a logical approach to clean the signal, validate the technique, and present the outcomes.

Expert’s Answer
To address this problem, we first recognize that biomedical signals like ECG are sensitive and require delicate handling. The most suitable approach involves using a bandpass filter that targets the known frequency range of the human ECG signal. In MATLAB, we recommend designing a digital Butterworth bandpass filter, which preserves the signal's shape while removing high-frequency noise and baseline drift.

Once the filter is implemented, the next step involves validating the results through signal visualization techniques. This includes comparing the raw and filtered signal plots and computing performance metrics such as signal-to-noise ratio (SNR) and root-mean-square error (RMSE). These assessments confirm the efficiency of the denoising technique without subjective judgment.

This example helps students apply theoretical filtering knowledge in practical biomedical scenarios and shows the effectiveness of MATLAB in handling complex real-world signals.

Sample Question 2

Topic: Optimization of Nonlinear Systems using MATLAB Tools

Question
A student working on a project related to machine learning models needs to minimize a nonlinear cost function with multiple variables. The task involves selecting a suitable optimization method, justifying the choice, and validating the result through performance metrics.

Expert’s Answer
Solving this challenge begins with identifying the nature of the cost function. For nonlinear systems, traditional linear solvers are inadequate. MATLAB’s fmincon function provides a powerful tool for constrained optimization of nonlinear multivariable functions.

The student is advised to define an objective function that computes the cost based on input parameters, and then apply fmincon by providing initial estimates and constraint definitions. This function iteratively adjusts the parameters to reduce the cost, respecting all constraints.

To justify the approach, the use of fmincon is preferred due to its robust handling of inequality and equality constraints, which is common in real-world applications like energy modeling or economic analysis. Validation can be done by analyzing convergence behavior, the final cost value, and plotting the optimization path to confirm it approaches a global or satisfactory local minimum.

This question enables students to develop hands-on experience with MATLAB’s optimization toolbox while aligning with advanced mathematical theory.
