  1. The signal we named it fundamental wave ; according to the fundamental wave, coefficients of the fundamental wave can be lined in a sequence. when the unique of the dissolve of the fundamental wave can be confirmed, the sequence of the coefficients can be regarded as one of representation forms of the signal itself ; theory of dissolvable signal shows that when order of the matrix of fundamental wave sampling equals to number of fundamental waves, the sequence of the sampling values from sampling points must be matched one by one with the sequence of the coefficients of fundamental waves. the sampling composed by sequences of the sampling values must be full sampling ; the relevant deductions of the theory of dissolvable signal shows that when sampling the signal, sampling frequency must be lager than the ratio of the number of fundamental waves to the occupation time of the fundamental waves ; to band - limited signals, when the fundamental wave is a sine signal, the results from the relevant deductions of theory of dissolvable signal is coherent to the classic sampling theory

    本文通過分析認為，當信號集中的任一信號可表示為一系列已知信號的線性代數和時，信號集便構成可分解信號集，已知信號稱為基波信號；對可分解信號而言，基波系數構成一序列，當對指定的基波信號集分解唯一確定時，系數序列本身便是信號的一個表示；可分解信號采樣定理指出當基波樣值矩陣的秩等於基波數時，則由采樣點處的采樣樣構成的樣值序列必與基波系數序列一一對應，從而由該樣值序列構成的采樣必為完全采樣；可分解信號采樣定理中的推論指出，對信號集進行采樣，采樣頻率必須大於其信號分解的基波數與其對應時長之比；對有限帶寬信號，若基波信號為正弦信號時，由可分解信號采樣定理推論給出的結論與經典采樣定理一致。
  2. At present, the most of vtr which are used in watch - control occasion for speciality are short of a uniform control - check - alarm system, which brings on the discommodiousness of operation and the user can not know the time of occurring a fault, which reduces the reliability of the watch - control system. therefor, at first, i carefully analyze the servo theory of the vtr which had been produced by chmavc with k mechanism to find out the work rule of the control signal ; second, take out some right control signal ; then for dealing with the problem of vtr in use for watch - control, i choose some right components to design the uniform control system for many special vtr with protel software. it mainly includes the following functions : operation functions of all vtr ( for example : power, play, ff, rew, stop, rec, eject, fwd, rwd, sp, lp ) was controlled by line at the same time ; in, the process of recording, when the tape walks to the end or stops by itself, the system gives an alarm and shows the number of the wrong vtr ; in the process of recording, the system gives an alarm and shows the number of the wrong vtr when the video signal from vidicon is losed ; the system controls all vtr to record on the non - working time when there is something wrong in the guarding section ; the system controls the video from vtr to switch to right monitor

  3. However, while bringing us a lot of benefits, it raises requirements for network interworking. as is shown in figures 1 and 2, if the order of the 2 mbits time slots is inconsistent on the 155 mbits paths, disorder will take place when these paths are interconnected, thus making impossible the functioning of the point - to - point 2 mbits links. hence the unification of the arrangement of the time slots of 155 mbits signals throughout the network

    正像圖1 、圖2中所示開通交換機中繼電路的情況，如圖中155mbits通路2mbits時隙排列不統一，在互連時就會造成2mbits時隙混亂，難以開通點到點2mbits鏈路，因此全網155mbits信號時隙必須統一排列規則，才能保證業務的順利開通，方便網路的維護。
  4. Most current algorithms only work well in special conditions, because of the abnormity of signals in the real world. now, the research in the ica arises much passion and the ica has brought about many applications. the primary results the writer has got are as the following : after a whiting process, it is a key to find an orthogonal matrix to throw away the high - order redundant information between components

  5. Firstly, a new joint filterbank precoders and decision feedback equalizers structure is proposed, and the corresponding optimization result based on the maximal mutual information criterion is derived. secondly, the concept of dt canonical model is proposed, which is very suitable for the task of blind signal processing based on the second - order statistical of the observations. thirdly, the methods of blind equalization and identification of the tv dispersive channels are researched systematically based on the proposed dt canonical model, and a subspace blind identification algorithm of the time - invariant channel matrix is developed

  6. We propose the joint filterbank precoders and decision feedback equalizers structure at first, by which the dispersive channel is equivallent into parallel independent flat fading subchannels such that the diversity gain of the receiver is increased. then we adopt the discrete - time ( dt ) canonical model to convert the problem of blind signal processing of tv dispersive channels into processing the time - invariant multi - channels model blindly, and discuss the problem of blind equalization and identification of tv dispersive channels based on this new model

  9. In order to understand the nature of the ecologist ' s investigation ， we may think of the density - dependent effects on growth parameters as the “ signal ” ecologists are trying to isolate andinterpret ， one that tends to make the population increase from relatively low values or decrease from relatively high ones ， while the density - independent effects act to produce “ noise ” in the population dynamics

    為了能理解生態學家們所從事的研究的性質，我們可以把那些作用於增長參數的密度依賴效應視作生態學家們力圖將其分離並予以解釋的「信號」 ，正是這一信號傾向于使種群從相對較低的數值遞增，或從相對較高的數值遞減；而與此同時，那些密度獨立效應起到的作用則構成了種群動態變化中的「噪音」 。
