基于VHDL的数字频率计的设计.pdf 基于VHDL的频率计设计 很好用的 希望要用的同志来下载 (基于VHDL的频率计设计 很好用的 希望要用的同志来下载 )

基于小波变换去噪，采用了vhdl编写，已经在和matlab上对比过，结果准确，而且大量的节约了时间，欢迎下载，可以在quartusii中查看RTL电路，可以在modesim中仿真出结果

主要是RS-232串行接口技术并且通过了串行收发器UART的开发实例演示了接口设计的基本步骤程序-Is RS-232 serial interface technology and, through a serial UART transceiver development of interface design examples demonstrate the basic steps of the procedure

this is a verilog code for root raised cosine filter

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.)
