Week 6

We have reached a standstill because we are not getting the circuit modulate the signal correctly.  Meaning that when we hook up the circuit to the oscilloscope and swipe our card, we are not getting a useful signal to determine differences between cards.

This signal is what shows up on the oscilloscope after we put a RFID card on there, this signal is supposed to look like a sine wave with a quick frequency change that would represent 1's or 0's.  This wave does not change for any RFID tag.  Currently we are working with fellow students and teaching assistants to figure out the problem, but are having little success.
