Upsamplers, DACs, jitter, shakes and analogue withdrawals, this is it.

RE: So help me out here

If you look at the video, one sees the stepped pulses connected via filtering. The stepped sine wave is a bit tongue in cheek, referring to sub optimal filtering. Some DAC measurements show a bit of a stepped looking sine wave vs. a smooth sine wave.

Here is a quick synopsis from AI regarding FPGA DACs:

FPGA DACs offer several advantages over traditional DACs, including:

Flexibility: FPGA DACs can be reprogrammed to perform a wide range of signal processing tasks, allowing for customization to meet specific audio system requirements.
Higher quality audio: FPGA DACs can provide improved signal-to-noise ratios and lower distortion, resulting in higher quality audio output.
Real-time processing: FPGA DACs can perform real-time signal processing, making them suitable for applications where low-latency is important, such as live sound reinforcement or gaming audio.
Cost-effectiveness: FPGA DACs can be more cost-effective than traditional DACs, especially for high-end audio systems.
Power efficiency: FPGA DACs consume less power than traditional DACs, making them suitable for portable audio devices.
Higher sample rates and bit depths: FPGA DACs can support higher sample rates and bit depths, allowing for more accurate audio reproduction.
Customization options: FPGA DACs can be programmed to support a wide range of audio formats and sample rates, making them versatile enough to be used in various applications.
