1 The main blocks are CIC anti-alias filter, decimator, DC canceller, Iterative multiplier, half-band filter, IIR low pass filter, DDS etc.

2 At last, this design of the decimator is implemented on FPGA hardware platform, and tested by oscilloscope and spectrum analyzer.

3 It consists of an analog modulator and a digital decimator.

4 Based on the theories of decimation, this dissertation analyses kinds of digital filters and decimation structures. With the MATLAB simulation, it determines the final structure of decimator .

5 A programmable decimation and interpolation ratio module onnected with multistage cascade integrator comb (CIC) filter is designed to implement high efficient decimator and interpolator.

6 Four half band filter (HBF) decimation modules are designed which can cascade connected to implement 2K decimator.

7 Martian Body Count" opened this week! It's the prequel to "Doctor Decimator Atomizes Mars.

8 This dissertation complete all the steps of the design and implement of decimator , and prove the possibility and flexibility of using FPGA to realize decimator both in theory and in practice.
