i have basic knowledge of matlab and took signal and system course. i want to do project like below. but dont know filter on matlab. are there any books i can learn fft commands etc.(dft, filter,signal system projects).

i skimmed lot of dsp books but they have just theoretical information and not practical.

  • \$\begingroup\$ As this exercise is probably exploring your understanding of the theory, you'll probably have to go back to those DSP books. The assignment specification still has the same spelling error in it... \$\endgroup\$

I would recommend a book called "DSP first" it explains practical DSP with examples using matlab



Help should start at home. You have plenty of tools at your fingertips

Seriously, one of your best tools will be the matlab help system. "help filter", or if that isn't enough, "doc filter" should yield tons of good information.

If you go into the documentation, you will also see a "getting started" guide for the signals toolbox. If you type "help signal", you get
