Figure 7-7: 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
The Figure 7-8 shows the calculation and conversion steps. The highlighted col-
umns contain the resulting I and Q values represented in Little endian format.
