The invention relates to a multistandard receiver circuit for analogue and digital broadcasting, particularly analogue and digital television broadcasting, having a demodulator arrangement with an input for applying digital or digitized values (d) for both analogue and digital broadcasting signals from a tuner () and with components and/or an algorithm for processing the values (d). Emphasis should be given to an embodiment and/or controller for processing the values (d) for all processing steps which are to be performed in the field of intermediate-frequency processing with shared components.

Multistandard receiver circuit for analogue and digital broadcasting

The invention relates to a method for processing of a signal (s), wherein desired data (d(f(N))) are received via a desired channel (N) of a plurality of frequency channels (N&#x2212;2, N&#x2212;1, N, N+1, N+2) and unwanted data (d(f(N&#x2212;2)), d(f(N&#x2212;1)), d(f(N+1)), d(f(N+2))) can be received on a neighboring channel (N&#x2212;2, N&#x2212;1, N+1, N+2) and wherein the signal (s) is sampled with a sampling frequency (fa) to avoid aliasing of the desired channel (N) in order to create digital data (d), wherein the sampling frequency (fa=2f(N&#x2212;1, N, N+1)) is set high enough for aliasing-free sampling of the desired channel (N) and at least one of the neighboring channels (N&#x2212;1, N+1).
