The Function of a Crystal Radio What is the first thing that comes into your mind when you think about the function of the radio? Is the first thing that pops into your mind the word ‘magic’? Despite the fact that it seems like it is magical and comes out of the air‚ radio and the use of the radio is very scientific. When broken down and analyzed‚ the function of the radio is more scientific than magical. The miraculous way that you can send out invisible information through thin air and can

music and favorite songs and many more applications. Nano radio is a fully functional‚ fully integrated radio receiver from a single walled nano tube. The nano tube serves simultaneously as all essential components of a radio: antenna‚ tunable band pass filter‚ amplifier and demodulator. A direct current voltage source as applied by a battery powers the radio. Using the carrier waves in the commercially 40-400 MHz range and both frequency and modulated techniques it demonstrated

twentieth century‚ the only ways to watch television were through over-the-air broadcasts and cable signals. With broadcast TV‚ an antenna picks up radio waves to transmit pictures and sound to your television set. With cable TV‚ wires connect to a set-top box or to your TV itself. These wires run from your house to the nearest cable TV station‚ which acts as one big antenna. Aside from a few options like satellite TV‚ broadcast and cable were -- and still are -- the main ways to watch television. New

Who will be affected by DTV Consumers who receive over-the-air television signals through antennas on television sets that are equipped with analog tuners – and who do not subscribe to cable‚ satellite or a telephone company television service provider – will be affected by the transition. At least 19.6 million households receive over-the-air signals exclusively in their

FM vs AM FM radio works the same way that AM radio works. The difference is in how the carrier wave is modulated‚ or altered. With AM radio‚ the amplitude‚ or overall strength‚ of the signal is varied to incorporate the sound information. With FM‚ the frequency (the number of times each second that the current changes direction) of the carrier signal is varied. FM signals have a great advantage over AM signals. Both signals are susceptible to slight changes in amplitude. With an AM broadcast
