12–85 Design Evaluation In a research laboratory, you need a bandpass filter to meet the following requirements:

Design Requirements: Passband gain: 10 ± 5%, B=

10 krad=s ± 5%, ω0 = 5 krad=s ± 2%, ωCL = 2 krad=s ± 10%.

Evaluation Criteria: Filter performance, parts count, use of standard parts, and cost.

The two vendors have responded with the designs shown in Figure P12–85.

As a research assistant, your supervisor asks you to evaluate the two designs and recommend a vendor. Which vendor would you recommend and why?
