Electromagnetics or Digital Signal Processing spring, techniques, directly, familiar

amy

I have three courses that I can choose from: Electromagnetics or Digital Signal Processing II or Semiconductor Physics and Theory for my spring?

Which do you suggest?  

    Firstly I do not work directly with radar/sonar so I'm shooting off the cuff here, and very much depends on the details.  

If you are going to be working on new techniques three things you will need to be familiar with are Fourier transforms, wave propagation and wave scattering.  Fourier is a part of all good courses on either EM or DSP, but I don't know about your specific courses.  I don't think DSP will teach you much about waves.

On the other hand if you are involved in building instrumentation DSP will be more practical.
