Sine cosine Wave generation using VIVADO only
Posted: Sat Jun 12, 2021 9:21 pm
Hello, I am new to Redpitaya board. I am trying to generate SIne cosine wave from DDS in Vivado.
The output of DDS is AXIS stream(16bit) and when i simulate this i can see a prefect wave. But when i connect the output of DDS to Redpitaya DAC(14bit) the generates wave is not same as the output of DDS.
The DAC output is cosine wave filled. When i go deep and check it is like small triangular waves forming a Cosine wave.
Please help me to get the correct waveform.
