In these cases, the 24-bit fixed standard is equivalent to the 24-bit mantissa, plus 8-bit exponent used in the 32-bit, floating-point version. |
In scientific notation, a number is displayed with its mantissa at the left and a two-digit exponent at the right. |
If you recall, run-of-the-mill DSPs typically store numbers as a floating-point, 24-bit mantissa and an 8-bit exponent. |
Answer Memory can store up to 12 digits for the mantissa and two digits for the exponent. |
Internal operations use 15-digit mantissa. |
In the JPL scheme, the total power of each sample is computed and stored in 2 bytes, one for the mantissa and one for the exponent. |
