本文利用UA0914声强耦合腔产生的同一声场条件,测量声强测量系统两通道之间的传递函数,进而对两通道间的相位不匹配误差进行修正。
The phase mismatch errors are corrected by measuring the transfer function between two channels at the same acoustic field provided with B&KUA0914 inside in-tensity coupler.
在近似相位匹配下,倍频效率相对于理想情况降低幅度不超过6%。
Furthermore, in the approximations of the exact phase matching, compared with the ideal case, the frequency-doubling efficiency reduced by multi-optical coatings is not more than 6%.
由于不匹配的电缆可引起过度的时钟相偏(Clock Skew),导致错误操作,所以相位匹配是有些高速数字电路中特别要注意的事项。
Phase matching is of particular concern with some high speed digital circuits, because unmatched cables may cause excessive clock skew, resulting in erroneous operation.
