Unformatted text preview: magnitude response falls below 50 dB. Annotate the given specifications in your plot using appropriate vertical and horizontal lines (see design example in handout #3). Submit a hardcopy of your plots. c) Create a plot that shows all pole and zero locations in the splane. For each complexconjugate pole pair, compute the poles’ distance from the origin ( ω P ) as well the corresponding Q P and summarize your results in a table. Convince yourself that the nulls in the magnitude response occur at frequencies equal to the magnitudes of the filter’s zeros. 3. Show that the group delay of a first order RC lowpass is given by the filter’s time constant multiplied by its squared magnitude response. This result is interesting and intuitive, as it shows that signals with lowfrequency content will see little phase distortion or “shape deformation” as they pass through the filter....
