We describe our experience introducing DSP concepts via an FPGA-based advanced digital design course. The students had previously taken an introductory digital design course and a continuous-time linear systems course; a few were taking an introductory DSP course concurrently. Through a series of weekly lab exercises, the students learned advanced FPGA design methods while progressively constructing...
Eight independent multi-rate signal interpolators, with real-time change of rate capability, were implemented on a field programmable gate array. The interpolator main building blocks are a cascaded integrator-comb (CIC) filter and the respective compensation filter. The latter performs a fixed rate change of 4 and was implemented as a 129 taps finite impulse response (FIR) filter. The FIR filter...
