I am student and my name is Oleg. I work on qualification task for GSoC 2018.
I should implement float-point support to als encoder.
A have some questions:
1)In documentation was written
"The floating-point sequence is modeled by the sum of an integer sequence
multiplied by a constant (ACF: Approximate Common Factor) and a
and in another part was written:
"If the input signal is 32-bit floating-point, input values are
decomposed into three
parts: An estimated common multiplier A, a truncated integer
multiplicand sequence Y,
and a difference signal Z.".
Can somebody explain what is ACF (I don`t find definition of this term
and how I can compute it?
2)What is the best method for testing encoder?
Link to documentation.
