While working with the data, user logic may store the data temporarily on SDRAM (or any other memory device for that matter). Of them all, the digital modulation technique used is Pulse Code Modulation (PCM). The macro PREC sets the number of bits that the code uses to store the fractional part of the input, which are the bits to the right of the “binary” point. Conclusion. The output of the ADC was fed into ideal DAC (programmed from Verilog-A), which was expected to come as the quantized version of the ramp input signal.
