Detailed Solution
Download Solution PDFIn digital modulation systems carrier parameters like phase, frequency or amplitude are varied with information signals.
According to this, there are three basic modulation schemes in digital modulation like:
- Amplitude Shift Keying (ASK)
- Frequency Shift Keying (FSK)
- Phase Shift Keying (PSK)
The advantages provided by digital modulation techniques include:
- Better performance.
- Better Error detection and correction efficiency.
- Better Signal to noise ratio so less prone to interference or noise
