Notch Filter Comparison To eliminate an interfering signal at 10 krad/s on a new product design, your consulting firm needs to purchase a notch filter with the following specifications:

Center frequency¼10 krad/s 0.5%

Bandwidth ¼ 200 rad/s 2%

Depth of notch (attenuation at v0) ¼ 50 dB min.

Two vendors have submitted proposed solutions as OrCAD graphics shown in Figure P14–64.As the owner, you want to select the best one. You must check that each circuit meets or fails every specification. You should also consider:

(1) parts count, (2) ease ofmaintainability and implementation

(fewer parts, number of similar parts, adjustments of potentiometers, standard values, and power usage),

(3) frequency domain response, and (4) cost. You should address each item for each design at least qualitatively.

Attach whatever software outputs you think will support your decision.
