* Question
| What are the main modulation methods used in RFID systems? |
* Answer
| There are usually three modulation methods used in RFID systems: ASK-Amplitude Shift keying for carrier amplitude modulation, FSK-Frequency Shift keying for carrier frequency modulation, and carrier phase modulation for carrier frequency modulation.Digital modulation called phase-keying (PSK-Phase Shift keying) |
