Answer Posted / shweta
modulation is needed to transfer the signal from
transmitter to reciever. As the signal passes from
transmmiter to reciever there are many external effects
such as noise and other factors which can degrade the
signal so there is a need of modulation so that the signal
cant become so much week that it cant reach the reciever.
If the signal is sent without modulating then it will get
degraded due to external effects.

What are applications of dsp?
The server is already having the list of IP addresses of all its authorized clients & if any client is requesting the server to do a task, it is sending its IP address(encapsulated in the packet) to the server.The server can easily match that IP address with that on its list and check if it's authorized client or not, then why we need inverse domain...........
