What is the name of the process that changes the instantaneous frequency of an RF wave to convey information?
Frequency convolution
Frequency transformation
Frequency conversion
Frequency modulation✓الإجابة الصحيحة
الشرح
Varying the instantaneous frequency of the carrier in step with the information signal is the definition of frequency modulation. Frequency conversion is a tempting name but describes mixing a signal to a different frequency, which carries no new information.
