Using the difference-equation method and all backward differences, design digital filters to approximate analog filters with these transfer functions. In each case choose a sampling frequency which is 10 times the magnitude of the distance of the farthest pole or zero from the origin of the “s” plane. Graphically compare the step responses of the digital and analog filters.
