Question 1: In embedded signal processing for aerospace systems, how do you deal with time-varying signals and perform adaptive filtering?

Which action should you take?

Choose only one option

By increasing the sampling rate to capture all variations

By using static filters and ignoring the variations in the signal

By applying a fixed filter and adjusting the gain manually
