Receiver Definition and 107 Threads

Hello fellow science enthusiasts. The other day I was thinking of a device for instantaneous transfer of data. You would have two entangled particles (or any even number but two just for simplicity), then you would "put" each one in two devices. An input is needed. For example a simple message...

Homework Statement The tuning circuit in an FM radio receiver is a series RLC circuit with a 0.200 µH inductor a. The receiver is tuned to a station at 104.3 MHz. What is the value of the capacitor int he tuning circuit? b. FM radio stations are assigned frequencies every 0.2 MHz, but two...

A photon or electromagnetic wave has the speed of light in vacuum and the distance, from the photons point of view, then becomes zero. The photon is then an energy exchange between particle A and particle B, and it is from the photons view at startpoint A and endpoint B at the same time. And it...

As far as I understand it... Each satellite transmits a signal that the receiver receives. This signal consists of (at least) a satellite identification together with a time-stamp of when the signal was sent and its position at that time. The receiver calculates the distance from the...

I have included a picture of what I would like to be able to make. I know that older phones operate on very specific MHz signals and that the newer ones are 2.4, or 5.8 GHz. I know there are scanners out there. But the purchase of one could be illegal, right? So why not make my own, to pick...

I have constructed a small one-transistor regenerative receiver, and I have been getting weird results with reception. I have noticed that simply touching parts of the radio, such as the antenna or around where the antenna is attached, will provide great reception. However, when I am not...
