- After investigating the relationship between generator measuring speed pulse and its on - load voltage at phase a , it is proposed in the thesis that we can obtained phasor of generators through messuring dividing frequency signal of generator measuring speed pulse
我们研究了发电机测速脉冲和其a相空载电势相位的关系，提出了只需测量与发电机同轴的测速发电机发出的测速脉冲的分频信号，经过计算就可以得出发电机相角的测量方法。 - The main work of the system can be divided into four main parts as the following : ( 1 ) 10 . 5ghz bandpass filter the main contradiction of filter is caused by its function of dividing frequencies . in order to properly divide frequencies , not only need passband ’ s attenuation to be as small as possible and stopbands ’ as big as possible , but also need a sharp and quick change between the attenuation of passband and stopband , thus to make their diversity obvious
这四个功能模块分别是: (一) 10 . 5ghz带通滤波器滤波器的主要矛盾是由它分隔频率的功能决定的,为了使分隔理想,一方面要求通带的衰减尽可能小,阻带衰减尽可能大,亦即通带和阻带的衰减差值要尽量大;另一方面要求通带和阻带之间衰减的变化应尽可能快,最好是陡峭的跳变,使阻带和通带的分隔十分明显。 - Without much theoretical deduction in this dissertation , we focus mainly on the several characteristics of wavelet , such as the localization in both the spatial and the frequency domain derived from the compact support in the two domains ; the rnultiresolution representation property ; and the octave divided frequency property , etc . after a brief overview of the principles and methods of image compression , video coding algorithms are introduced including 3 - d wavelet video coding and 2 - d wavelet video coding . based on the above , the research of this dissertation consists of three aspect : firstly , the 3d - spiht algorithm is modified which optimizes bit allocation
具体说，本论文包括以下内容：首先，本文分析介绍了小波理论，文中没有过多的理论推导，而是从小波具有的一些特性，如时频局部性、多分辨率分解特性和倍频程频带分解特性入手，力求对小波变换有一个宏观的了解。其次，介绍了基于小波的图像编码的原理和常用的编码方法。最后，介绍了基于小波的视频编码的方法，一种是基于3 ? d小波视频编码，另一种是基于2 ? d的小波视频编码方法。
