Lecture 8 - Timing Constraints

Metastability is a problem that arises when an external input NOT synchronised to the system clock is fed into our synchronous circuit. Since the input signal could change anytime relative the the clock edge, metastability will occur. It could also happens when a signal crosses from one clock domain (Clock1) to another clock domain (Clock2).

LAPLACE TRANSFORMS AND ITS APPLICATIONS

† Time delay The substitution of t ¡ ‚ for the variable t in the transform Lf(t) corresponds to the multiplication of the function F(s) by e¡‚s, that is L(f(t¡‚)) = e¡s‚F(s) II. APPLICATIONS OF LAPLACE TRANSFORMS This section describes the applications of Laplace transforms in the areas of science and engineering. At

The width at half maximum gives the damping factor γ. 4 Fourier transform is complex For a real function f(t), the Fourier transform will usually not be real. Indeed, the imaginary part of the Fourier transform of a real function is Im f˜(k) ∞ = f˜(k)−f˜(k)⋆ 2i ...
