Opposite of Pack K Bits - Converts a byte with k relevant bits to k output bytes with 1 bit each, located in the LSB.
In other words, this block picks the K least significant bits from a byte, and expands them into K bytes of 0 or 1.
Example:
k = 4
in = [0xf5, 0x08]
out = [0,1,0,1,1,0,0,0]
Each input byte produced four output bytes (that are either 0 or 1). Remember that there is no item type of "bit" in GNU Radio, so we have to use bytes to represent single bits.
