I am testing the example projects coming with the VDSP5.1, for the project "21489 AD1939 C Block-Based Talkthru 48 or 96 kHz" the input is sine wave of 1kHz.
A breakpoint is set in the function "void handleCodecData(unsigned int blockIndex)" to observe the input data stored in RxBlock_A0 and
RxBlock_A1. However, I am confused with the figure plotted with these data as shown below, the data format is int.
The TDM has four slots for receiver, so I decimate these data by four and replot the figure, but it is also not an entire sine waveform.
Could anyone give me some explanation on this?
