Show answer & explanation
Correct answer: B
In Frequency Modulation process, the frequency of a carrier wave is modified in accordance with the binary data from the baseband signal:
0 (Low Bit): Represented by a lower frequency sine wave (longer wavelengths).
1 (High Bit): Represented by a higher frequency sine wave (shorter, more compressed wavelengths).
Constant Amplitude: Unlike Amplitude Modulation, the height of the waves remains uniform throughout the signal.
