    Hello Gilberto ,

    Fantastic explanation.
    I was spend many time today to understand this concept.
    Finally You help me a lot to figured out.
    Now I understand it. and Finally can get some sleep.

    Thanks again

    Cheers.

    Hello Gilberto,
    thanks a lot for example and explain.
    Many part are much more clear to me.
    Some part a bit confused to me.
    "LFO ranges from -1 to 1"
    What I understand range -1 to 1 amplitude is full cycle of 1Hz , thus -1 to 1 = 1Hz.
    or do i to think -1 is half and 1 is half thus 2Hz ?
    i don't understand What makes 2Hz ?
    Do i miss something before to understanding this concept ?

    Hello everyone,
    I have some question in Ring modulation
    Can some body explain to me some theory in Ring modulation .
    here is question.
    Q: How come carrier Frequency phase cancel out in RM ?

    For instance, if the carrier is 900 Hz and the modulator is 500 Hz, we will get two sidebands; one at 400 Hz (900 - 500) and one at 1400 Hz (900 + 500) and Carrier Frequency cancel out ?
    How come ? There is no out of phase in this signal , then how do we get understand this ?
    I was search on internet and could not find an answer.

    last question in AM

    suppose we use range -1 , 0, 1 amplitude.
    there is two difference range of amplitude . one is -1,0,1other one is 0,1

    a range of amplitude -1 ,0, 1 is longer than 0,1 rate because signal go through 0 , 1 ,-1 ,0, and 0,1 has only 0 to 1 and 0.
    unipolar has short rate than bipolar.
    but actually if i modulated two signal with those range of amplitude and compared.
    the result was opposite.
    bipolar is more fast than unipolar.
    i think bipolar takes more time to hear the signal than unipolar
    because the signal go through 0 and -1 , o to 1 that makes more time than unipolar.
    I am curious how come range -1 , 0, 1 is fast than 0, 1 .
    maybe i am completely lost this section.or completely wrong approach.
    I really wanna understand this. can someone help me ?
    thanks in Advance
    lu.
