Each data point (represented by a square) on the sampled signal in Figure 10.23 represents one analog-to-digitalconversion.
采样信号上的每一个数据点(一个小方块)图10.23代表这一次模数转换。

The first essential step in analog-to-digitalconversion is to sample an analog signal.
模数转换关键性的第一步是对模拟信号进行采样。

The basic elements of a control system using a digital computer consist of the data-gathering devices which perform analog-to-digitalconversion on data form the system which is to be controlled;
