crossover designs การใช้
- Some loudspeaker crossover designs aim to stabilize impedance at high frequencies by including Zobel networks.
- Crossover design expert Siegfried Linkwitz said of them that " the only excuse for passive crossovers is their low cost.
- Second, statistically efficient and so require fewer subjects than do non-crossover designs ( even other repeated measures designs ).
- Another challenge as the planar magnetic design had a bottom end of 100Hz and it was key to make the crossover design seamless.
- Using crossover design, researchers can further increase the strength of their results by testing both of two treatments on two groups of subjects.
- Invented and trademarked in 1976 as " Time Alignment ", the crossover design was influential in loudspeaker development from the late 1970s throughout the 1980s.
- In another study, 73 subjects were randomized to receive valaciclovir 1 g daily or placebo for 60 days each in a 2-way crossover design.
- Nearly all crossover designs have " balance ", which means that all subjects should receive the same number of treatments and that all subjects participate for the same number of periods.
- DaimlerChrysler's crossover design, the Jeep Varsity, " blurs the line between boulevard and boulder, " said Tom Gale, executive vice president of product development and design.
- In the late 1970s, Bill Putnam of Universal Audio worked with Ed Long and his patented Time Alignment crossover design to fix the long-standing problem of the two bandpasses not being aligned in time at their crossover point.
- This is usually due to poor crossover designs or choices ( too high crossover point or insufficient crossover slope ) used in many computer and home theater systems; localization also comes from port noise and from typically large amounts of harmonic distortion in the subwoofer design.
- Some potential for attracting youthful buyers can be seen in the 2003 Toyota Matrix, a funky vehicle known as a crossover design because it combines elements of a car with a small SUV . Toyota is running advertising showing spies on a manhunt struggling to describe the car but unable to find the words.
- Cone tweeters today are often relatively cheap, but many of those in the past were of high quality, such as those made by Audax / Polydax, Bozak, CTS, JBL, Tonegen and SEAS . These vintage cone tweeters exhibited very flat frequency response, low distortion, fast transient response, a low resonance frequency and a gentle low-end roll-off, easing crossover design.
- They are commonly used in speaker crossover design ( due to the moderately large voltages and currents, and the lack of easy access to a power supply ), filters in power distribution networks ( due to the large voltages and currents ), power supply bypassing ( due to low cost, and in some cases, power requirements ), as well as a variety of discrete and home brew circuits ( for low-cost and simplicity ).
