Your company issued a request for proposals listing the following design requirements and evaluation criteria.

Design requirements call for a high-pass filter with a passband gain of unity and a cutoff frequency of 150 Hz10%. The filter input is driven by a sensor with a 50-Ω source resistance.

Evaluation criteria are filter performance, parts count, power consumption, and cost. The three vendors have responded with the designs shown in Figure 12–15

(a). As a junior engineer, you have been asked to evaluate the designs and identify the best design. Which vendor would you recommend and why?
