采样率小于一个连续时间信号最大频率的2倍时就叫undersampling,欠采样,根据抽样定理,当fs>=2fmax,也就是oversampling,过采样时,数字信号才能重建成原来的模拟信号,欠采样重建会发生混叠-Sampling rate of a continuous-time signal is less than the maximum frequency of 2 times is called undersampling, bandpass sampling, according to sampling theorem, when fs

空气湿度报警器,顾名思义,是用来测量空气中的湿度的仪器,他通过一个湿敏电容和一个频率输出电路对空气湿度进行检测,把湿度变化转变成频率输出。再通过单片机把输入的频率转化为湿度百分值并通过LCD显示出来,使人可以通过显示清楚地看到空气的相对湿度。在单片机编程时可以预先设定一个限定值,当环境湿度达到设定的湿度值时电路报警,同时发光二极管变亮,达到湿度报警的目的。-Air humidity alarm, as the name implies, is used to measure humidity in the air apparatus, he humidity through a capacitor and a frequency output circuit for detection of air humidity, the humidity changes in the frequency of the output into. Through the single-chip frequency of the input into a percentile and humidity through the LCD display, one can clearly see through the display of the relative humidity of air. Single-chip can be programmed in advance to set a limit value, when the environmental humidity to achieve set alarm circuit humidity values, while LED light changes to achieve the purpose of humidity alarm.
