Relation between Levi-civita and Kronecker- delta symbol Homework Statement definition of εijk εijk=+1 if ijk = (123, 231, 312) εijk = −1if ijk = (213, 321, 132) , (1.1.1) εijk= 0,otherwise . That is,εijk is nonzero only when all three indices are different. From the...
Hi, in some books the ##\nabla## symbol is used for the Laplacian ##\frac{d}{dx^2}+\frac{d}{dy^2}+\frac{d}{dz^2}## while others use the ##\Delta## symbol for this. What is the correct custom for this usage? SemM ...
Die Dirac-Funktion ist eine Funktion, deren Wert bei Null-Eingabe unendlich und bei allen anderen Eingabewerten Null ist. Wir können keinen unendlichen Wert plotten, also müssen wir ihm einen endlichen Wert geben und ihn dann mit der Funktionplot()oderstem()in MATLAB darstellen. Die Funktio...

Simple Integral: Complex exp --> delta function My Professor has written this down but I'm having some trouble of precisely where this is coming from: \int\psi^*_{f}(\boldsymbol k')\psi_{f}(\boldsymbol k) d^3\boldsymbol r = (2\pi)^3\delta(\boldsymbol k- \boldsymbol k') ...
Incremental Delta-Sigma (I-DS) analog-to-digital converters (ADCs) are one of the best candidates for integrated sensor interface systems when it comes to high resolution and power efficiency. Advanced architectures such as Multistage noise shaping (MASH) or extended counting (EC) I-DS ADCs can...
If the second stage is implemented as a first-order I-DS ADC as in Figure 3a, it needs a separate the CoI1 reconstruction filter indicated by the symbol 𝐻𝑟𝑒𝑐2(𝑧)Hrec2(z). If the second stage is implemented as a simple quantizer, there is obviously no reconstruction filter...
