In the previous article, we've talked about the need for modulation and we've also talked about analog & digital modulations briefly. In this article, we'll discuss the main difference between analog and digital modulation in the case of digital modulation it takes a digital signal for modulation whereas analog modulator takes an analog signal.
Advantages of Digital Modulation over Analog Modulation
- Digital Modulation Techniques are Bandwidth efficient
- Its have good resistance against noise
- It can easily multiple various types of audio, voice signal
- As it is good noise resistant so we can expect good signal strength
- So, it leads high signal-to-noise ratio (SNR)
- Alternatively, it provides a high data rate or throughput
- Digital Modulation Techniques have better swathing capability as compared to Analog Modulation Techniques
- The digital system provides better security than the analog. Because encryption and decryption of digital signals are quite easy.
