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 ā€œsā€ plane. Graphically compare the step responses of the digital and analog filters.
