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
