FM without 'pink noise'

In noise parlance, 'white' noise is the term that is usually used for non-bandlimited noise (ie, 'broadband noise'). "Pink' noise, on the other hand, is a term used to refer to bandlimited noise. In practice, anything that comes out of the audio channel of a communications receiver is really 'pink' noise, as the bandwidth is limited to a few KHz. On the other hand, the noise that is incident at the antenna or generated in the front-end is much broader in bandwidth and is more deserving of the term 'white' noise.

I wanna know how can I get the FM signal without that nasty 'pink' noise. I'm not using any kind of external antenna. Greetings!! |
