5 Questions
What is modulation?
Modulation is the process of impinging useful information on the carrier and demodulation is the recovery of that information from the carrier at the distant end near the destination user.
According to the IEEE, how is modulation defined?
The IEEE defines modulation as 'a process whereby certain characteristics of a wave, often called the carrier, are varied or selected in accordance with a modulation function.'
How is modulation visualized?
Modulation may be visualized as a mapping operation that maps the source information onto the bandpass signal, s(t).
What is the modulating function?
The modulating function is the information baseband described previously.
What is the modulated signal called?
The modulated signal is called the bandpass signal s(t).
