How does one make a simple radio with a transmiter and a receiver? Can someone better explain a passive RFID tag? Answered
I use a fm transmitter and a fm receiver to connect my tv to my computer speakers. The device is not very cost effective and I tried to make my own transmiter and receiver that had one frequency. I then learned about passive RFID tags and wondered how it could both transmit and receive a radio wave. And it only uses a memory source with an antenna in the form of an inductor. I began to wonder if I could make a tranmiter and receiver like an RFID tag. There is so much about radios in general that I still can't comprehend.
