Question 2. Select the correct statement regarding the modulated ASK waveform. a. There is no difference between the OOK and ASK waves b. It is seen that logical "1s" and "Os" are represented by different carrier wave amplitudes c. Unlike OOK where logical data is represented by a voltage or the absence of a voltage, ASK represents logical data using different voltage levels operating at the same frequency d. both b and c are correct statements
