What is meant by detection of modulated carrier wave? Explain briefly steps for detection?
what is ground wave propagation
Which mode of propagation is used by short wave broadcast services having frequency range from a few MHz upto 30MHz? Expain diagrammatically how long distance communication can be achieved by this mode.Why is there an upper limit to frequency of waves used in this mode?
Sir plz..give the answer fast!!!!
Why do we use manganine wire in potentiometer?
write two factors justifying the need of modulating a signal.
what is square law device?
Sir, Why moon cannot be used as a communication satellite?
I need to prepare project on Communication System ...can someone help me on it
It is based on the CBSE....and i need it for submission for the partial fullfilment for the requirement for studies in Physics 10+2.
please help me select toic or to prepare.
your help is heartly welcome at: thomasofjnv@gmail.com

What is space wave propagation?
explain about downlink and uplink????
A TV tower has a height of 100m. How much population is covered by the TV broadcast if the average population density around the tower is 1000 persons per sq km?
what is the necessity of modulation?
