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 s-plane. For each complex-conjugate pole pair, compute the poles distance from the origin ( 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 filters zeros. 3. Show that the group delay of a first order RC lowpass is given by the filters time constant multiplied by its squared magnitude response. This result is interesting and intuitive, as it shows that signals with low-frequency content will see little phase distortion or shape deformation as they pass through the filter....
