RF noise in digital equipment... (detection with AM radio?)

ash_dac · 22nd April 2006, 10:02 AM

Hi,

I could only find a few sources on the web. Any suggested readings on RF at an introductory level?

From the little reading I have done it seems we have conduction, and radiation sources.

Would it be possible to detect the radiated RF noise with an AM radio or would the circuit below be better ?
(my PC noise is picked up by my AM radio)

My DIY non-oversampling TDA1543 DAC has been proven te be an quite effective AM-radio transmitter.. at some point I could actually listen with my AM-radio to the CD being played with my DAC......

What could you hear the music or was it noise?
