Mathematics of Radio

My interest in radio began when I was a boy and discovered I could pick up distant AM radio stations at night. I was shocked when I could hear foreign languages on the radio and had no idea at first how this was happening.

In college I became interest in signal processing, and later did DSP for several companies. Now DSP and radio overlap in numerous ways, such as Software Defined Radio (SDR).

I have an amateur radio license, extra class, and my call sign is KI5TUZ.

Here are a few blog posts I’ve written about radio and related topics.
