You are the head engineer for a small start-up and a client asked for a filter with the following specifications: a third-order Butterworth low-pass filter with a cutoff frequency of \(2 \mathrm{krad} / \mathrm{s}\) and a dc gain of o dB. Three of your junior engineers were tasked to design the product that your company will manufacture. Their designs are shown in Figure P14=51. Which would you select and why? Of important consideration is performance, number of parts, fewer distinct parts, fewer nonstandard parts, power usage, and anything else that would win your company the contract.
