Recursive digital filtration and spectrum analysis

The problems of building recursive digital filters and recursive analyzers is examined. The structuring of digital filters out of electronic computers using the appropriate programs is discussed and performed. An analog-digital converter is used to convert a continuous signal into a sequence of digits. The advantages and shortcomings of digital filters compared with analog filters are examined. The importance of the Laplace transformation in calculations is discussed and methods for recursively achieving transfer functions are examined.
