    When data from one point is sent to another through a carrier, its first converted into signals.

    These signals are modified to reflect digital data.

     

    An analog signal is characterized by its amplitude, frequency, and phase. There are three kinds of digital-to-analog conversions:

     

    • Amplitude Shift Keying

      In this conversion technique, the amplitude of analog carrier signal is modified to reflect binary data.

      Amplitude Shift Keying

       

     

    • Frequency Shift Keying

      In this conversion technique, the frequency of the analog carrier signal is modified to reflect binary data.

      Frequency Shift Keying

     

    • Phase Shift Keying

      In this conversion scheme, the phase of the original carrier signal is altered to reflect the binary data.

      Phase Shift Keying
