Este documento describe el gran poder e influencia que tienen las palabras. Las palabras pueden curar o herir a las personas y determinar su felicidad o desgracia. Es importante pensar detenidamente antes de hablar y usar las palabras con cuidado y compasión para no causar daño a otros o a uno mismo. Las palabras reflejan nuestro interior y pueden construir o destruir.
Esta es una diapositiva que nos hace reflexionar en la manera como debemos medir nuestras palabras hacia nuestros semejante ya que con una palabra podemos construir o destruir.
VECTOR VS PIECEWISE-LINEAR FITTING FOR SIGNAL AND POWER INTEGRITY SIMULATIONPiero Belforte
The basic concepts of two fitting methods suitable for signal and power integrity simulation up to multi-gigabit/sec rates are presented. The traditional method is based on Vector Fitting (VF), a well known technique to approximate complex functions of frequency by a rational polynomial expression in terms of poles and residues. The second is a full time-domain approach mainly based on behavioral models supported by the Digital Wave Simulator.
PWLFIT/DWS advantages over VECTFIT/Spice can be summarized with the 3S acronym: SIMPLICITY, STABILITY and SPEED.
SIMPLICITY because the pwl fitting of a time-domain behavior is a very fast, explicit and intuitive process that doens't need the solution of implicit equations as required by Vector fitting. Time-domain S-parameter of actual devices in matched conditions shows simpler behaviors than the corresponding impedance in the frequency domain.
STABILITY because the use of Digital Wave processing is intrinsically very stable. Extracted pwl behaviors processed by fast convolution within DWS are unconditionally stable if the source behavior is stable. This means that NO numerical conditioning is required. As known Vector Fitting often require numerical conditioning to get stable results.
SPEED: time-domain pwl fitting is a very fast process. DWS simulations are also very fast even at very small time steps required by multigigabit system analysis. DWS/SPICE typical speedups are 100X for traditional VF derived RLC-TL circuits and up to 10000X when using pwl Behavioral Models in time domain.

One of the most famous Czech writer, Mr. Karel Capek, which left among others the word ROBOT to future generations, has among others left following explanation named: WHY I AM NOT A COMMUNIST. It can be named WHY I AM NOT A POLITICIAN as well and I hope google translater will do good job for you, to understand this core wisdom.
15. Ante ello tenemos que cultivar
cualidades de amor, verdad y gratitud,
creando un sólido mundo interior en
donde la bondad y la verdad
brillen; para luego extender este
mundo interior a las personas de
nuestro alrededor.
