FIR滤波器设计方法 (1)采用的是窗函数设计法和频率采样法， (2)用计算机辅助的切比雪夫最佳一致逼近法设计。
6.2 模拟滤波器的设计
理论和设计方法相当成熟，有若干典型的模拟滤波器可以选
择。如：巴特沃斯(Butterworth)滤波器、切比雪夫(Chebyshev)滤
波器、椭圆(Kllipse)滤波器、贝塞尔(Bessel)滤波器等，这些滤波 器都有严格的设计公式、现成的曲线Ha和H(jΩa (图)jΩ)表供设计人HH员aa (j使ΩΩ)) 用。

ZX3-90PI12-inch Two-Way Passive90° x 50°, 600W Weather-Resistant Loudspeaker SystemGeneral Description:Technical Specifications:Key Features:DVX3121 12” LF Transducer with Forced Air • CoolingND2 2” Voice Coil, 1” Exit Neodymium • Compression Driver90° x 50° Coverage Pattern• 600W Continuous (2400W Peak) Power • HandlingHigh Sensitivity, 131 dB Maximum SPL • Adjustable Monitor Angle (45° or 55°)• 2 Anchor Plates for Single Stud Fittings and • 7 Integral Suspension Points Available in Black or White• All Weather IEC 529, IP44, & MIL810 • Environmental Specs Full Line of Accessories•The Electro-Voice® Zx3 is the new standard of no compromise audioperformance and versatility in a simple to use, compact package. The ZX3-90PI features a molded polymer enclosure that is inherently water resistant. The addition of a multilayer grille with hydrophobic cloth and a gland nut input connection allows for a highly weather resistant system.At its heart are the transducers. First is the DVX3121 high performance low frequency transducer. EV used advanced computer aided design tech-niques to create forced air, directional voice coil cooling for high power and efficiency. Finite element analysis was used to optimize the suspension and magnetic structure for long, linear travel to provide low distortion and greater LF extension. These features and details, such as forged magnetic components and special materials, provide reliability with a 500W power rating in a lightweight transducer. Next is the ND2, a 2-inch voice coil com-pression driver based on neodymium motor structure to allow for maximum output while reducing size and weight to a minimum. Its precision phasing plug and titanium diaphragm provide better HF performance, while the integral heatsink provides cooling for high power output.The high tech enclosure uses injection-molded high-impact polypropylene structural foam to make the Zx3 incredibly durable. The enclosure geometry elements have been carefully designed to provide maximum rigidity and bass response. By design the Zx3 is also a perfect solution for stage moni-tors by allowing two angles (45° or 55°) without any additional accessories.Two coverage patterns are available; 60° x 60° coverage for long-throw and cluster applications, 90° x 50° coverage for wider coverage or shorter distances.The Zx3 is equipped with two anchor plates for rigging with single stud-fittings, along with two more possible anchor plate attachment points on the bottom. For permanent suspension or attaching brackets, the Zx3 also has two M8 inserts on the top and bottom, two under the handle, and one on the back of the enclosure, for a total of 7. All versions are available in black or white.Freq. Response 1 (-3 dB):58 Hz - 15 kHz Freq. Range 1 (-10 dB):48 Hz - 20 kHz Rec. Hipass Frequency:50 HzAxial Sensitivity 1:97 dB (1W/1m)Max.
