In addition, this receiver is so sensitive and powerful that it can clearly pick up AM carrier waves as weak as 10-to-the-power-NEGATIVE-10,000 watt-per-meter-squared. This receiver also has a robust signal processor that can eliminate clipped-waveforms [such as square waves], spikes, clicks, pops, hiss, and random noise even at those trivial wattage levels. After eliminating those unwanted signals, the carrier wave is amplified. This receiver has an astronomically-powerful amplifier which amplifies those extremely-soft carrier waves until the resulting modulation signals will be just loud enough for the human ear to coherently detect. Following this amplification, the carrier waves are demodulated to modulation waves -- the stuff we "hear" -- and then sent to loudspeaker so those onboard can hear those sounds. Equally important, the 2-GHz receiver is pointed away from the earth to assist in preventing the pickup of signals generated from Earth. If I am on this spaceship, what will I most likely hear on the radio? The sound of absolute zero, which sounds a lot like the sound of absolute infinity, except that morons at Viacom pick up the tab, rather than morons at AT&T. Thanks, Radium |
