A low-pass filter is specified with a cutoff frequency of 10 Hz. Calculate the time constant τ and derive the transfer function.
💡 Hint: Use the formula for τ first.
Discuss how increasing the order of the low-pass filter to 2 affects the filter's response compared to a first-order filter.
💡 Hint: Think about how the filter behaves across different frequency ranges.
