Verilog HDL语言编写异步FIFO(Verilog HDL language, asynchronous FIFO)

本文介绍一种波导双模双带滤波器的设计方法。(This paper presents a new class of dual-mode dualband filters in which each polarization is dedicated to a selected band. The equivalent circuit is a parallel combination of two inline networks that represent each polarization. A transmission zero is generated between the two bands by properly adjusting the relative orientations of the input and output coupling apertures.)

说明：  matlab代码，利用Farrow结构设计分数延时滤波器，滤波器阶数和个数可分别进行设置，利用最大最小准则近似。(Matlab code, using Farrow structure design fractional delay filter, filter order and number can be set separately, using the maximum and minimum criterion approximation.)

FPGA控制AG9226进行采样的代码,并用signaltap测试了一下其正确性(FPGA control AG9226 to sample the code, and use signaltap to test the correctness of the demo.)

一个简单的探测110三位的探测器，用逻辑图和vhdl描述，包括实验报告和测试图。-a simple survey of 110 three detectors, and a logical map vhdl description, including reports and experimental test plan.

FIR滤波器：自定滤波器的类型（低通，高通或带通）、设计指标（通带截止频率、通带波纹、阻带截止频率、阻带衰减） 1、根据指标选择合适的窗函数，用窗口设计法设计符合指标的FIR滤波器；并验证其性能是否满足预定指标。 (FIR filters: Custom filter types (low pass, high pass or band-pass), design specifications (passband cutoff frequency, passband ripple, stopband cutoff frequency, stopband attenuation) 1, according to indicators choose the right window function, using the window design method of FIR filter designed to meet the targets and verify that its performance meets the set targets.)
