Modulatin' away...

Amplitude Modulation...

So here we are, Summer Quarter at Renton Technical College in the Industrial and Robotics course and studying... communications?  What is up with that?

Well, pretty much no matter what we do... we have to communicate in some way, shape, or form.  Wireless communications are a pretty hot topic these days and I'll do anything to eliminate the need for cables and wires draping across my space!

The phonecam picture for today is a shot of an AM signal shown on the oscilloscope.  AM is a method of modulating a low frequency signal (voice, music, etc.), with a high frequency (radio) signal.  It can then be transmitted across the airways to your radio, where it is demodulated and let's you listen to the news.  Imagine the newscasters having to shout the news to their listeners...  like the town cryers of old.

Fun stuff!
