[DSP program] adc_dac_1 DL : 0: 典型的采样数据DSP系统实际模拟到数字的转换之前，模拟信号一般要经过某些种类的信号调节电路，这些信号要执行像放大、衰减和滤波这样的功能。需要用低通/带通滤波器把不需要的信号从有用带宽中消除掉，并能防止混叠发生-Typical sampled data DSP system, the actual analog-to-digital conversion before the analog signal in general has to go through certain types of signal conditioning circuits, these signals to perform as amplification, attenuation and filtering such functions. Need to use low-pass/band-pass filter the unwanted signal from the useful bandwidth to eliminate out, and to prevent the occurrence of aliasing

[DSP program] DSPshiyandaima DL : 0: 实验一一、观察采样引起的混叠。（来源：p57 习题1-3）设模拟信号为，t的单位为毫秒(ms)。 1. 设采样频率为3kHz，确定与混叠的采样重建信号。 2. 画出和在范围内的连续波形。（因数字计算机无法真正画出连续波形，可用较密的离散点的连线来近似。） 3. 分别用和在两信号波形上标记出3kHz采样点。两信号波形是否相同？采样后的两序列是否相同？ -11 experiments to observe the sampling due to aliasing. (Source: p57 Problem 1-3), based analog signal, t' s in milliseconds (ms). 1. Based sampling frequency of 3kHz, sample identification and reconstruction of signal aliasing. 2. Draw and the continuous wave within the scope. (Because digital computers can not really draw a continuous waveform, can be more dense, discrete points to approximate the connection.) 3. Respectively and the two signal waveforms 3kHz sampling points on the mark. Two waveforms is the same? Sample after the two sequences are the same?
