Digital Modulation Techniques
Can we combine two or more modulation techniques?
It is possible to combine ASK, FSK and PSK. Combining different modulation techniques increases the number of symbols available which in turn increases the bit rate, because increasing the number of symbols increases the number of bits per symbol.
Can message signal be analog signal and carrier wave digital in Digital Modulation?
Yes, one type of Digital Modulation is Pulse Modulation where the message signal is analog and the carrier is digital whose amplitude, width and position is changed with respect to amplitude of message signal.
Can we use Frequency Division Multiple Access (FDMA) in Digital Modulation?
FDMA can be used with both Analog and Digital Modulation techniques. However FDMA is predominantly used with Analog Modulation since it can support TDMA and out of FDMA and TDMA, TDMA is commercially viable and has high spectral efficiency. Hence TDMA is used in Digital Modulation.
Digital Modulation Techniques
Modulation is the Fundamental Process in Communication Systems, In Modulation Low-Frequency Message Signal Blends with High-Frequency Carrier Frequency to Enable Efficient Transfer of the Signal. In this article, we will be going through Digital Modulation Techniques, First we will start our Article by Defining Modulation, Then we will go through the Three types of Digital Modulation techniques with Their Wave, At Last we will conclude our Article With their Application, Advantages, Disadvantages and Some FAQs.
