The real time proceedings and the algorithms become more and more important. A digital filter is important technique to raise
frequency resolving accuracy. The base of the digital signal processing is lectured.
The technical elements are commented on to understand that digital signal proceedings are introduced to the many fields.
This aim is acquire of sampling theorem, some transform operations, filter processing, impulse response, frequency characteristic, FFT and correlation.
