Hello
I am using the Altera Megacore NCO Compiler and need to dinamically adjust the phase of the generated sine wave.
The core has an input called phase_mod_i[] which is used for this purpose. The problem is that I don't know the relation between the desired phase adjust (in degrees) and the number I need to input in the core.
Is it linear? As in:
Input (with 15 bits of angular precision) / Phase Difference (degrees)
000000000000000 / 0
100000000000000 / 180
111111111111111 / 360 (or 0)
Can anyone help me please?
Thank you
Thiago

Hi, i'm a student university and i made a QPSK modulator with Altera Stratix II and i don't understand how set NCO for an phase modulation and how define the constallation mapper....
thx for support
