M 个信号星座点\left\{s_1,\cdots,s_M\right\}构成 signal constellation(信号星座图)。 显然,如果我们确定了所有的\phi_j(t),那么就可以将s_i(t)和s_i互相转换。s_i(t)用s_i表示被称为 signal space presentation,包含信号星座图的向量空间被称为 signal space。 换句人话说,就是把原来的一组向量...

As shown inFig. 13.50,vestigial sideband modulation(VSB) is employed for the luminance, with a picture carrier of 1.25MHz relative to the VSB left edge. The space between the picture carrier and the audio carrier is 4.5MHz. The audio signal containing the frequency range from 50Hz to 15kHz...
On the other hand, from mathematical point of view, a set of signals can be looked as a vector space, and all of the filters can be looked as another space, therefore, the linear signal processing progress can be looked as the actions between the signal space and thefilter space. As sh...
The "Miracle" ofk-space The diagram below shows a hypothetical FID obtained from an MR slice through the upper abdomen. 如下图所示,假设有一个 FID 信号,来源于 MR 上腹部某个层面。 The FID has undergone accelerated decay due to the action of a dephasing gradientG(x)that is directed along ...

The signal has a name so the signal can be identified and referenced by name in a data log. (SeeSave Signal Data Using Signal Logging.) Such a signal name can contain space and newline characters. These characters can improve readability but sometimes require special handling techniques, as ...
The system has been designed to enable the emission of a broad class of signals, and to apply digital communications technology as used in radar and space communication. Signals include different forms of conventional frequency modulation sweep or “chirp” signals (Edelmann and Helbig, 1984), in...
A very useful representation of the z-transform is obtained by plotting these poles and zeros on an Argand diagram; the resulting two-space representation being termed the ‘z-plane’. When the poles and zeros are plotted in this way, they give us a very quick way of visualising the charac...
