Question 3. Select the correct statement regarding the modulated FSK waveform. a. The modulated signal does not accurately represent the message because the amplitude of the modulated signal does not change with changes in the logical data. b. The modulated signal indicates changes in frequency, but no changes in amplitude. Therefore, the modulated signal is distorted and does not accurately represent the logical data. c. It can be seen that logical “1s” and “0s” are accurately represented by changes in carrier frequency; therefore, the modulated signal accurately represents the logical data. d. There are no accurate statements above.
