    Analog signals are being used and changed to represent the analog data.This process or conversion is being called as Analog Modulation.

     

    Analog modulation is performed when bandpass is needed.This can be done using three approach:

     

    Analog Modulation

     

     

     

    Amplitude Modulation

     

    In this modulation, the amplitude of the carrier signal is modified to reflect the analog data.

     

    Amplitude Modulation

     

     

     

    Frequency Modulation

     

    In this modulation technique, the frequency of the carrier signal is modified to reflect the change in the voltage levels of the modulating signal (analog data).

     

    Frequency Modulation

     

     

     

     

    Phase Modulation

     

    In the modulation technique, the phase of carrier signal is modulated in order to reflect the change in voltage (amplitude) of analog data signal.
