    Closed: Re: transformer inductance

    The best tool for this is the network analyser.
  3. Closed: Re: Required Circuit to convert Square wave from 5v to 12v

    This won`t work because you`ll lose the square pulse unless you have it regulated. Use an opamp circuit.. that will do it. You are misleading the house and it is against the standing orders of this...
  4. Closed: Re: Help me design a pre-amp circuit for audio signals

    I should say you better not use high pass and low pass filters as you are looking at a very small scale low powered amplifier and it is almost impossible to design a preamplifier with filters at...

    Closed: Re: A Universe from Nothing

    The basic explanation to this question is explained in elementry quantum mechanics. It is called "nothingity times infiningity". i.e. zero times infinity gives something, if and only if energy is...
  6. Closed: Re: Property of Integration :: Please confirm it

    I think you have got the answer from @albbg. However, his explanation is based on numerical values. If you are not satisfied with it, the best way to think about it is by using the Riemann integral...

    Closed: Re: where coil store energy??

    You have to keep in mind that we are dealing with the rate of change of flux or rate of change of current. So you need to keep the fluxuation going on or else you will lose it.
  8. Closed: Re: Is that a Formula???

    Good work mate. It does work. You may publish this to a journal like LMS or AMS.

    Closed: UHF antenna with circular polarization

    I want to design a UHF antenna for a RFID doorway reader with circular polarization of at least 30 deg. My approach was printing a yagi-uda antenna on a PCB with a coaxial port. However, it had less...

    Closed: Re: vswr limites

    I think you need to think about having a BALUN transformer or similar balancing technique in order to obtain lower mismatch loss--thereby making the reflection coefficient tending to zero and hence...
