    How autocorrelation is related to psd and fourier transform?

    Re: autocorrelation Hi azaz104, I dont know the exact paper which describe the mathematical equation physically, but I am attaching a paper which gives you the usage of above mathematical equation in audio/speech codec applications. I think this paper helps you to understand it physcially...

    High or low frequency

    Hi, Higher freq wave are less prone to noise will travell longer distance without much loss of power. And it will strongly depends on medium too. Thanks Animesh

    Performance differences between open and shorted stubs

    open stub and short stub Hi, you can use any stub either Open or short for matching but implementing short is easy as compare to open that's why most of the RF guys prefer short stub. Thanks Animesh

    Network analyzer calibration

    Hi I would suggest you to ask your VNA provider/dealer from where you have purchased your VNA. Because different companies has same calibration principle but that have different process and rules so better go for that documents which corresponds to your NA. I can tell you about procedure how...

    how can i make microstrip antenna in the first step?

    Hi, Under microstrip antennas, which shape are you looking for like microstrip slot, microstrip circular patch, rectangular etc... Because depending upon shape you can start design antenna acouring to spec. Let take microstrip slot antenna for example , for that you need to calculate using...

    What kind of polarization does this microstrip patch antenna have?

    Re: antenna pls help Hello Danesh, Visit http://rfry.org/ . This URL contains several papers which will be usefull for you to get better understanding of antenna fundamentals. By the way figure does't shows it a circular polarozation. Thanks Animesh

    which be better MOM or FDTD

    Hi Both MoM and FDTD methods have advantages and disadvantages. I had worked on microstrip slot antenna and I would suggest to go for MoM for microstrip antennas. As MoM are used for simulation of antennas or arbitrarily shaped metallic structures. MoM also provides good isolations if...
