Hello,
I know how the chip (which contains the information gets power). By radiowaves which by Faraday's law induces a voltage in a coil(receiveng antenna). But I don't understand how it transmittes data to the RFID reader. I never designed those chips, but I can think that the chip is a register (ROM) which contains 0 and 1. Something like in a computer. So how to transmit such data? I have read about it on the web, but it's not described for the transmitter.
So from my understanding we can transmit only harmonic signals, but if we have a DC value of voltage, can we transmit DC signals?
Thank you.
