FPGA Horizons London- October 6th and 7th 2026 - get Tickets here. The $99 Artix UltraScale+ Explorer Board - learn more here Over the last few weeks we have looked at some of the basics of DSP in FPGA, from filters such as FIR and IIR to DFT and FFT. Continuing this exploration of basic DSP elements there is a common challenge we often face in DSP, that is changing the sample rate of a signal. Example of the need to change the sample rate include working with a delta-sigma m
