    E. Codec modulation

    Explanation:

    Codec is used to encode digital signals for transmission.

    Amplitude modulation uses the amplitude of the carrier wave to encode or modulate the information for transmission.

    The phase of a wave changes with respect to the amplitude, so information is modulated with the phase angle as amplitude changes in phase modulation.

    Bandwidth modulation is a form of modulation that encode the information of a fixed bit size based on the frequency of the carrier wave. It is similar to frequency modulation, but frequency modulation modulate a signal wave information.
