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.

Parameters

K
Constant for unpacking bits
