What are some good resources for learning about DSP (including the mathematics and algorithms necessary for actually understanding these resources)?
Let's assume that my math skills are rusty from lack of use as well, so a roadmap along the lines of:
would be nice and hopefully result in DSP skills and knowledge approaching "competent".
If you are familiar with programming, then Digital Signal Processing nothing very different, but focussed on processing a lot of input data with some algorithm. From very simple to vry difficult. Nobody expects that you know everything from the start. You are in a learning process.
Topics include sampling, impulse response, frequency response, finite and infinite impulse response systems, linear phase systems, digital filter design and implementation, discrete-time Fourier transforms, discrete Fourier transform, and the fast Fourier transform algorithms.
Signal processing, has seen much better times in its past and is continuing in the present. More and more, the future of signal processing is looking very bright and long-lasting in time and in other dimensions—long- lasting because any information in nature and wherever it is available could be looked at as a signal.
