More DSP Resources (and maybe a little math)

Filed under: Electronics,ham radio — Cranky Sysadmin @ 2:51 pm
  • A Visual Intuitive Guide to Imaginary Numbers. Imaginary numbers used to make my head hurt. If you’re shooting for your General or Extra class ham license, they will make your life easier. They’re also the basis for a lot of DSP work.
  • Quadrature Signals. Also explains complex numbers and then does a deep dive into quadrature signals which are used in a lot of aspects of DSP.
  • Bores Introduction to DSP. Somewhat math heavy with summations and integrals, but still an approachable introduction.
  • dsPIC tutorial and “Robotics 3.1“. Dig around on these blogs for basic information about how to use the dsPIC30 series PIC DSP processors. Most of the examples don’t seem to need the DSP portion of the chip, but it will get you started without going to basic PIC microcontrollers.
  • AE6TY. This ham does a great job of explaining his SDR implementation using DSPIC and some ADC’s. Don’t miss his Intro2SDR under the papers section. His DSPExplorer application looks nice too but I’ve only taken a cursory glance at it so far.
