Summary
The Encode CCSDS 27 block is a 1/2 rate, k=7 convolutional encoder that takes a packed stream of bits (as bytes from the Random Source) and produces twice as many output symbols (0 or 1). Each input byte (8 bits) generates 16 symbols, packed into 2 bytes.
With a Random Source generating random bytes (0 to 255), the input bits are pseudo-random, leading to a pseudo-random sequence of output symbols after encoding.
After Unpack K Bits (K=1) and Char To Float, the output should be a stream of 0.0 and 1.0 values, which should appear as a rapid alternation when visualized.
