  • AMPLITUDE MODULATION (AM)
    The basic modulation technique is an analog modulation called amplitude modulation (AM). You will learn the basic principle of analog modulation and the type of amplitude modulation.

  • ANGLE MODULATION
    Angle modulation can be divided into phase modulation (PM) and frequency modulation (FM). This modulation technique is also analog modulation. However, this technique has been widely used due to its advantages. PM and FM are inter-related.

  • PULSE MODULATION
    Digital modulation came after analog modulation. It offer a lot of advantages especially on noise insensitivity and easy to be stored and reproduced. This topic introduce the basic concept of digital signal and digital modulation.

  • DIGITAL MODULATION RADIO
    Digital modulation radio process is similar with analog modulation. In this modulation, the signal information is a digital signal while the carrier signal is high frequency sinusoidal signal. If the signal is analog, it need to be converted into digital signals prior to modulation process.

  • MULTIPLEXING
    Multiplexing is a process to send more than one signals simultaneously using the same channel. The main purpose is to increase capacity of users. There are several advantages using this method that will be discussed in detail.
