encode_2bit_base¶
- baseband.base.encoding.encode_2bit_base(values)[source] [edit on github]¶
Generic encoder for data stored using two bits.
This returns an unsigned integer array containing encoded sample values that range from 0 to 3. The conversion from floating point sample value to unsigned int is given below, with
lv = TWO_BIT_1_SIGMA = 2.1745
:Input range
Output
value < -lv
0
-lv < value < 0.
2
< value < lv
1
lv < value
3
This does not pack the samples into bytes.
