the concept of modulation
Why?
•More efficient to transmit E&M signals at higher frequencies
•Transmitting multiple signals through the same medium using different carriers
•Transmitting through “channels” with limited passbands
•Others...
How?
•Manymethods
•Focus here for the most part on Amplitude Modulation (AM)
