Probably the biggest use would be for modelling hardware or software that
uses Chebyshev filters (modelling is a topic of considerable research these
days). Other reasons for selecting Chebyshev over Butterworth would include
reducing the worst-case group delay by being able to use a lower filter
order to meet a specified magnitude response, and for designing your own
hardware-based or DSP-based filters, in which filter order is a significant
cost factor.
