Map vector of integers to vector of bits
Communications Toolbox / Utility Blocks
The Integer to Bit Converter block maps each integer (or fixedpoint value) in the input vector to a group of bits in the output vector.
This block is singlerate and singlechannel. The block maps each integer value (or stored integer when you use a fixed point input) to a group of M bits, using the selection for the Output bit order to determine the most significant bit. The resulting output vector length is M times the input vector length.
