In a multiplexed sensor system, which component is directly responsible for routing one of several sensor inputs to a shared output line?

What is the main advantage of using hardware multiplexing in a sensor system with many sensing elements?

Using conformal tactile textiles*, it is possible to get a dense, wearable 2D map of pressure on the foot (pictured above - yellow = unloaded, blue = loaded). What two-dimensional DSP tool might you use to analyse these data and detect whether a person pronates or supinates?

Why have we chosen a Laplacian-of-Gaussians filter?

Which threshold should you use to maximise accuracy? (Answer format XX.XX) 

What is the accuracy at the sigma and threshold above (give as a percentage - XX%)

Process the images using a Laplacian-of-Gaussian. Which filter sigma (integer) gives you the best accuracy?

Applying a filter kernel to a 2D dataset in the space domain to perform operations like smoothing or edge detection is typically implemented using which mathematical operation?
