Programming of coefficients
The coefficients are expressed in different value ranges and in decimal notation (refer to the
previous paragraphs). In order to be programmed they must be converted into a
[-1, +1) range and in hexadecimal notation (
). This can be achieved with the
following procedure:
if CoeffDecValue>0
if CoeffDecValue<0
where CoeffI2CValue is the final decimal value to be converted into hexadecimal notation
while CoeffDecValue is the coefficient value (in decimal notation) to start from.
