Having in mind a physical meaning behind a discrete-time signal, the physical quantity can always be recovered by multiplying the numbers of the sequence by a reference value of this quantity. This is exactly what digital-to-analog converters do. In the following, the input sequence of the

The sampling theorem is a prerequisite for the pulse code modula

There are no design tables available with normalised coefficients of prototype filters that could be easily adapted to special design specifications. So each filter design has to pass, in principle, a complete mathematical design procedure. According to the chosen approxim
