Figure 12-2: Principle of creating a waveform manually
The following steps outline how to create the waveform file
SICO.wv
:
1. Calculate the sine and cosine values, e.g. use the
SICO.cpp
program.
The result is stored in the file
SICO.txt
.
Figure 12-3: Contents of SICO.txt: first column Sine (I), second column Cosine (Q)
2. Convert the values from the file
SICO.txt
into binary format consisting of 16-bit
signed integer numbers. The numeric range between –1.0 and +1.0 corresponds to
the modulation range of the waveform 16-bit D/A converter of -32767 to +32767.
+1.0 ->
32767 ->
= 0x7FFF
0.0 ->
0 ->
= 0x0000
-1.0 ->
-32767 -> = 0x8001
