hello, I hope to make a simple rfid that can transmit 20 different frequencies and receiver that can decode those signal transmitted from rfid. I hope that rfid without any transistor so i can design it very small I don't need it long range. I hope max 10 meter range. please post your Idea
Hi everyone.
- A 10x probe is meant to isolate the circuit from the scope as much as posible (using pasive probes), but the problem is the impedance mismatch (a 50 ohm termination at the scope input is not enough).
- A 1x probe is not 50 ohm, and has low bandwitdh.
- so it seems that a simple...
