Abstract
A device and method are provided for implementing digital baseband separation of composite video signals with reduced memory requirements. The method and device require that only the composite signal be stored in a large delay element. Multiple quadrature demodulators are employed to generate multiple delayed complex baseband signals. Therefore, no large complex baseband delay element is required.
