    what is unipolar pam

    hi audioguru! i guess we hardly use PAM for digital modulation i guess PTM has more advantages. and know one thing,i just came to know that there is a fallacy in the name itself of PCM(it is not a modulation scheme)! cheers!

    Increased voltage!

    thats why the people follow such practices. anyhow is there any way to get an increased voltage ? my very vague guess goes in the direction of negative swing which earth might be providing -130 to 130V makes it 260V right? anyone in support? ur comments ante?

    Increased voltage!

    hi ante! people of indian villages normally follow this practice when voltage is low (130 V)but most appliances run here on 230V. I have single phase 2 wire in my house. there also it works.

    Antenna and TV standard

    hi audioguru! do the video(AM) and audio signals(FM) in a TV come from the same antenna. i guess they differ in frequency by a large amount. how do they travel after antenna in same single wire?

    Increased voltage!

    come on friends! views on my qustion of increased voltage when groung dipped in moist mud or clay? I guess some where the voltage is swinging in negative direction. no?otherwise it cant happen. it is simply strange buddies! anyone who would like to experiment?

    Mobile camera!

    hi guys! does anyone of u know that we can see an IR led glow with the help of a mobile phone or any other digital camera. does anyone know why is it so? if anyone comes to know pls share ur views. thanks! ;D

    Increased voltage!

    the topic deviated! Actually i had read about an experiment which people in rural areas of our country do ... in india mains voltage is 230V(standard) but in rural areas it falls to say 130V which makes the people impossible to run their appliances. they generally put the ground wire in wet...

    Increased voltage!

    hi all! today i noticed a strange phenomenon. when i dip the grounding wire of my household in water the line voltage increases in magnitude . how could that be?from where does the excess energy comes? thanks in advance...

    DSB power

    Strange boss! ultimately its the market to the end user! So strange of you.audioguru! could u please post an answer for my query in Circuits/general requests/Frequency selection please! thanks!

    DSB power

    i guess i cited same example for audioguru when we were discussing the difference between science (physics) and maths more precisely scientist and engineer, scientist says its possible to build while engineers say NO! ;D

    missing some basic theory

    perhaps u really go out for lunch! he he he ;D

    DSB power

    hi yousef! i didnt understand what did u say! why cant we integrate a time function? i guess theres no problem in it.

    time beeper

    I guess a piezobuzzer has a diaphragm and it oscillated at a fast pace when supply is connected across it. i guess the frequency of oscillations would be too high at say 30V thats why it burns out.Generally most electronic devices are rated at max 12 -15 V.I use this mark as the distinction with...

    missing some basic theory

    an when the food is same ,the one who is more hungry will eat up most of it. the same is the case with a series circuit. the lower resistance draws more current froma fixed power supply.

    what is unipolar pam

    hi jitender! if i am not mistaken u are talking about pulse amplitute modulation.The amplitude of same ,symmetrical pulses is varied in accordance with modulating signal.just like AM .but it is pulses as carrier rather than a sinusoid. ;D

    time beeper

    hi audioguru! i guess it could even burn out at 6V.why do u call it extra loud? are u sure?

    time beeper

    google search did not help me too! anyway what was ur project and which problem were u facing?
