    FM WAVE PROPAGATION

    hi all! hi bandwidth and high frequency differ. does working at high frequency ensure high bandwidth for the device? what do we desire,high bandwidth or frequency? prateek

    TRY OUT A MUSCLE STIMULATOR! CIRCUIT IS AWAILABLE ON ALL MAJOR BIOMEDICAL INSTRUMENTATION SITES,ANOTHER CHOICE IS ELECTRONIC STETHOSCOPE(AWAILABLE ON THIS SITE)DO U HAVE AMPLE TIME? PRATEEK

    FM WAVE PROPAGATION

    hi guys! i have heard that bandwidth is precious ! save it! why is it the case when we are safely moving towards higher end of spectrum(upto tera hz)????? IS BANDWIDTH REALLY A THING TO PRESERVE???? PRATEEK

    SIMPLEST LIE DETECTOR

    I GOT THIS CIRCUIT OF A SIMPLE LIE DETECTOR AT WWW.AARONCAKE.NET BUT IT DOES NOT WORK PROPERLY NEITHER DO I KNOW HOW TO OPERATE IT.I HAVE ALREADY MADE IT.ANY SUGGESTIONS FOR IMPROVEMENT? PRATEEK

    SERIAL PORT

    be careful to use the statement outport address once and inport statement twice to handle the problem of repeated readings in quick basic(a serious flaw in qb not C) PRATEEK

    FM WAVE PROPAGATION

    hi audioguru! very less interference at very high frequencies.microscopic pocket antenna to transmit,what else do we desire?wat is the problem at such high frequencies?can we expect our radio services to run at few Ghz in near future? prateek

    FM WAVE PROPAGATION

    hi alun and audioguru! can i conclude that high frequency waves dont travel far because they mostly travel line of sight but have the advantage of low noise over loe frequency signal??????????plz reply prateek

    FM WAVE PROPAGATION

    AUDIOGURU! IF I HAVE 5mV SIGNAL (AMPLITUDE) AND I TRANSMIT IT AT 2 FREQUENCIES SAY 100Hz and 2Ghz .do u think that the two will be equally affected by noise?if not,which one is affected more? if noise effect is independent of frequency we could not be fighting for and paying huge bucks for...

    question about variable resistors??

    IS IT ALSO POSSIBLE TO CONTROL BRIGHTNESS OF BOTH BULBS BUT IN A VARIABLE MANNER RATHER THAN CONNECTING ALL 3 IN SERIES? PRATEEK

    FM WAVE PROPAGATION

    hi audioguru! i have read that the world today is craving for bandwidth. thats why we are constantly moving towards higher end of spectrum just like GHz range in satellite communication. But it comes with a disadvantage that higher frequencaties are more prone to noise.is it true that high...

    FM WAVE PROPAGATION

    audioguru! how do you rate the idea of using low level modulation in this circuit? in that case we can almost blindly chose the amplifier prateek

    FM WAVE PROPAGATION

    audioguru! as far as i know we in india can transmit upto 100 mW in F.M range(88-108)Mhz. how can i ensure that my transmitted power does not exceed 100mW? for frequencies i think that we have to purchase the bandwidth from government. prateek

    FM WAVE PROPAGATION

    hi audioguru! i exactly meant the way you thought..Did u have to purchase the frequency used by you from the authority or one is free to chose any frequency at which transmission is done.IN short can i make a transmitter that works at 115 Mhz. well beyond f.m range and that too without...

    FM WAVE PROPAGATION

    hi audioguru! dont u think it will be a good idea to use a band pass filter just before modulator in your modified ckt.if yes pls try it out and let me know the results. can i have the reciever ckt too .how are u testing it? have u made your own reciever too or r u using conventional f.m...

    FM WAVE PROPAGATION

    hi chaitanya! my query was why do high frequency waves have such a property and low frequencies have different properties of reflection? prateek

    FM WAVE PROPAGATION

    most books on electronics communication systems clearly write that F.M waves do undergo more distortion in reflection of the ground than low frequency a.m waves.why is it so?in other words why a.m waves dont travel line of sight and why f.m does? prateek
