Abstract
Channel selection of a received signal is first of all carried out, in the process, by way of an analog channel selection filter. The signal is then converted to a digital discrete-time and discrete-value signal. Finally, the continuous-time and continuous-value signal profile is determined on the basis of a mathematical reconstruction using the zero crossings {ti} and the phase values {φ(ti)=ki·π/2, kiεN0}, with a mathematical reconstruction algorithm using a function system {φ(t−k)}.
