    pattern generator

    hi all! i am trying to generate a pattern to be displayed on the screen of a  black and white(monochrome TV) i need to generate a square wave of any integer multiple of 15625 Hz. Can anyone put up the exact working schematic.i feel that i can use  a  crystal and two not gates .thats it but i...

    ANTENNA RADIATION PATTERNS

    ya i do have the mathematical equation. it may be any equation but i am unable to generate the plot. can u help? the equation may be say y=sin(sin(x)) basically  i need a 3-d plot showing all the lobes.

    10 A FET

    HI AUDIOGURU! me too have just heard !!! we are in same boat.actually somebody recommended me and i am  not in touch with that person.i searched a lot for this device on the net but could not find one.do tell me if u get thanks prateek

    REQUIRED A GTO

    Hi all! I  need a GTO which conducts  at 12 V anode supply and 10 V of gate supply and should be able to give atleast 40 Amps of current to drive automobile headlights. THANKS IN ADVANCE PRATEEK

    audioguru fm transmitter

    hi audioguru! in am any transmitter or receiver or any other transistor circuit for that matter, does the collector supply of the transistor matter? how does oe decide how much supply to chose? 5V ,6V,12V? what can happen if it exceeds or lowers below the desired value?

    10 A FET

    hi audioguru! there are ofcourse many FETs operating on 300 A even but i need the one which operated from a 10V supply between drain and source as higher supplies are not commercially available here.another of my requirements is that it should saturate at a gate voltage pulse of 10V.can u...

    10 A FET

    hi all! i need an FET or any other transistor for that matter which goes into saturation at 10V input gate voltage and gives out a drain current of about 20-30 Amperes.The drain source voltage is 10V I need to drive car lights with this amount of current. can anyone help me?

    Bass Box

    hi audioguru! we often see the concept of virtual short b/w the 2 input terminals and we also see that both are at near ground potential. het wait if that is the case,where is the signal to be amplified???? pls tell me... ::)

    help needed

    besides this u can get  a few software projects as well ... from www.howstuffworks.com and search on the net for C codes and DSP algorithms as well

    what is function of capacitor

    i cant see the diagram very  clearly but still i can say that some times the capacitors have to be used for supply filtering too i.e to remove the ripples in a dc supply.the purpose may not look  very promising to a newbie!!!

    help needed

    what all programming languages do u know? are u interested in a hardware project(circuit design or schematic making) do u know C? there are a lot of hardware projects on www.aaroncake.net

    Input Filter circuit design needed

    do u wish to smoothen it to dc with an aim to remove all the ripples in the supply? if that is the case i guess a simple electrolytic capacitor can do ur job.good luck!

    finding emf

    hi there! the method which i just told in my last post is popularly known as the method of balancing of EMFs.u can search on the net for the same....the standard EMF which u use must be grater than the EMF to be measured...... We use the unknown EMF to balance the potential drop across a wire...

    finding emf

    thru a standard known emf cell and a potentiometer wire. i guess we do this experiment in school here in india did u do this?
