Transmission Definition and 708 Threads

i was reading an article about the new RFID tags that could replace ATM cards. these tags respond to query via a radio tranmission. the tag then uses the power that was in the initial radio transmission to reply back to the system. how are the tags using the power from the transmission? can...

Hi folks, quick question, i have just read a small snippet on data transfer that has sparked some thoughts. Basically it was this: Baseband transmission, one carrier frequency is used and the electrical signal is applied directly to the wires. Broadband transmission, signal is sent by...

If an ensemble of quantum partcles, with energy E, traveling in x direction encounter a very wide potential barrier V0 > E, the ensemble wavefunction will exponentially decay within the barrier. I thought that meant that there was a small probability of detecting an electron within the...

I am building a custom chopper, hardtail frame. I am learning as I go and I had a video to help me but my vcr ate it. Does anybody know about transmission mounting or anything about bikes?

Yesterday I was a at special SARS conference and here what I have learn and did not see on the news: - Virtually all infected people show SARS viruse in the fecals matter only 50% show SARS viruses in the resporatory system. Therefore SARS viruse would be transmitted from air to air, fecal to...

I tried to work out the transmission coefficient and the reflection coefficient for a case similar to the one referred by this website: http://www.chembio.uoguelph.ca/educmat/chm386/rudiment/models/barrier/barsola.htm but instead this time, I reverse the situation and now, that particle...

How does a hybrid transmision work? Both automatic and standard

I have seen the shifters for the slapstick transmissions(automatic and standard) I am just wandering how do they work?
