"Radio" or "Radio Waves" are energy expended in the form of electro magnetic radiation. More specifically the term "Radio" refers to a specific frequency pattern of that radiation. This is how Radio broadcasting works. "Microwaves" are a said to be all radio frequency between 300Mhz and 30 Ghz. Thus microwave is a specific class of "Radio Wave". For more in depth explanations research the theroys of Heinrich Hertz.
NO
The difference between energy and power signals...power signals have infinite energy but finite power..
The difference between slow and fast FHSS is the speed of the transmitting radio signals. Both have signals that are difficult to intercept.
What the difference between envelop and coherent detection of AM signals
Yes!
Power vs Signals
now they are better now they are better
It signals the difference between successive sample sizes
They can be interfered by other transmission signals
microwave
Pfft. No. It uses Radio Signals. Not Radiation.. Radiation is from the Sun and Microwave Signals. :)
A copper cable transports electrical signals. An optical cable transports light signals.
