RL Filters

High pass filter[edit] When the inductor is in parallel with the load while the resistor is in series with the inductor and load, this creates a high pass filter. High pass filter has a transfer function {\displaystyle H(j\omega )={\frac {v_{o}}{v_{i}}}={\frac {j\omega T}{1+j\omega T}}}{\displaystyle T={\frac {L}{R}}} Frequency response of High pass filter {\displaystyle \omega =0.v_{o}=0}{\displaystyle \omega =\omega _{o}.v_{o}={\frac {v_{i}}{2}}}{\displaystyle...

Filters and its Types-Electronics

A Low Pass Filter is a circuit that can be designed to modify, reshape or reject all unwanted high frequencies of an electrical signal and accept or pass only those signals wanted by the circuits designer. In other words they “filter-out” unwanted signals and an ideal filter will separate and pass sinusoidal input signals based upon their frequency. In low frequency applications (up to 100kHz), passive filters are generally constructed using simple RC (Resistor-Capacitor)...

Green Computing

I. Introduction Green Computing has become an innovative way on how technology and ecology converge together. With the recent years many industries and companies have turned their attention in realizing how going 'green' can benefit public relations, reduced costs, and lowering global emissions from industrial manufacturing. Though the term green computing covers a vast range of methods, from energy saving techniques, to the study of materials used in our lives, it all fundamentally breaks down to finding ways to not damage or...
