Impedance

this program evaluates the impedance and phase velocity in the shielded microstrip transmission line. program helps to view the effect of dimension of shielding used. Platforms: Matlab

This application can be used to easily calculate the resistor values needed to achieve a specified attenuation in a controlled impedance environment. Platforms: Windows

Zfit(data)Plots the impedance DATA which has to be a 3-columns wise matrix [FREQ, RealZEXP, ImagZEXP]. Impedance, admittance, capacitance and modulus representations in the complex plane are then pushbutton obtainable.The others usages are described in the help lines with examples too...

Introduction?*A* ImpedCalc is a free transmission line impedance calculator. The result is based on formula not 2D field solve, so it can only confirm the accuracy in a relatively range. Accuracy evaluation?*A* Surface Microstripe?*A* when H=4.5,T=1.2,Er=4.2 and change W. The result is... Platforms: Mac

Many NoSQL databases, mostly the Document based ones, translate into Python as a list of dictionaries, right? So why do us developers try to staple document databases into Django's traditional style relational introspection and tools? It's like we're trying to add object impedance mismatch to...
