Distribute elements of input vector alternately between two output vectors
The Deinterlacer block accepts an even length column vector input signal. The block alternately places the elements in each of two output vectors. As a result, each output vector size is half the input vector size. The output vectors have the same complexity and sample time of the input.
This block accepts a column vector input signal with an even integer length. The block supports the following data types: int8, uint8, int16, uint16, int32, uint32, boolean, single, double, and fixed-point. The output signal inherits its data type from the input signal.
The Deinterlacer block can be useful for separating in-phase and quadrature information from a single vector into separate vectors.
If the input vector has the values [1; 5; 2; 6; 3; 7; 4; 8], then the two output vectors are [1; 2; 3; 4] and [5; 6; 7; 8]. Notice that this example is the inverse of the example on the reference page for the Interlacer block.
If the input vector has the values [1; 2; 3; 4; 5; 6], then the two output vectors are [1; 3; 5] and [2; 4; 6].
