这是一个将模拟量转换成数字量的VHDL源代码，能够转换正弦波，三角波，方波；通过设定一个阀值，再用比较器比较实现的！-This is an analog quantity into a digital representation of the VHDL source code, to convert sine wave, triangle wave, square wave by setting a threshold, then comparator compares the implem

基于VHDL语言方波转换三角波的程序 仔细进行调试 可用-Based on VHDL square wave triangle wave conversion program
