* Question
| What are the benefits of using subcarrier modulation in RFID systems? |
* Answer
| Each time the debug tube has a short on-time, the impact on the electronic tag power supply is small; the total on-time of the controller is reduced, and the total power loss is reduced; the spectrum of useful information is distributed near the sub-carrier instead of near the carrier, which is easy to read.The writer extracts the transmitted data information, but the RF coupling loop should have a wider frequency band. |
