The minimum and maximum values attained by an analog data signal in each of successive sampling periods are determined by alternately operative amplitude detectors which produce and store a corresponding minimum and maximum signal for each of these periods. A generator produces a ramp signal which ...
使用?你的意思是数字信号处理吗?因为自然模拟信号是连续的,所以如果需要控制、检测、滤波、调制等工作,则需要用将之转化成电子元件可识别的0,1模式数字信号,这样处理器或者电脑才能对之进行各种处理。当然不变成数字信号也是可以进行信号处理的 比如收音机,电视等就是直接对模拟信号进行解调放大。
