Design Evaluation Your company issued a request for proposals listing the following design requirements and evaluation criteria.
Design Requirements : Design a low-pass filter with a passband gain of \(9 \pm 10 \%\) and a cutoff frequency of \(90 \pm 10 \%\) \(\mathrm{krad} / \mathrm{s}\). A sensor drives the filter input with a \(1-\mathrm{k} \Omega\) source resistance and an open-circuit voltage range of \(\pm 1.6 \mathrm{~V}\).

Evaluation Criteria: Filter performance, parts count, use of standard parts, and cost.
The two vendors have responded with the designs shown in Figure P12-66.
As a junior engineer, the project manager asks you evaluate the designs and recommend a vendor. Which vendor would you recommend and why?
