Phase detection in digital PLLs, or mixing in SDR receivers.
To appreciate the primer, one must understand why FPGAs dominate high-performance DSP. Traditional approaches include: Xilinx University Program - DSP for FPGA Primer...
– Past students have built:
You’ve mastered the Z-transform. You can convolve signals in your sleep. You’ve even written MATLAB scripts to filter out noise from a sine wave. But then comes the dreaded question in an interview or lab session: Phase detection in digital PLLs, or mixing in SDR receivers
