what is modulation? what is its need.
What is meant by grating element?
why skywave not used in the transmission of tv signals?
What is the difference between point to point and broadcast communication modes. Give one example
define sky wave propogation
why ar microwaves used in RADAR?
when modulation index is kept less than 1 distortion dosent occur.......how and why???? plxzzzzzzz reply briefly........nd fastly.......
draw a block diagram of a simple amplitude modulation.explain briefly,how amplitude modulationis achieved.
Explain why high frequency carrier waves are needed for effective transmission of signals?
what is square law device? what is the function of this?
Please suggest me any me hurry up!
i am wating your reply?
State two factors by which the range of TV signal can be increased??
why do we need to modulate the frequency?
what are the limitations of amplitude modulation?
explain detection of amplitude modulated wave
