Wireless Data Access and Supervisory Control System
The analog and continuous time signals measured by the sensor and modified by the signal conditioning circuitry must convert into the form a computer can understand. This is what is referred to here as data acquisition. The continuous analog voltages could be directly used to control the analog mechanism. However, deals specifically with the sampling and quantization techniques for using the information from the user to control a digital computer. The effects of such a process on the waveform received from the signal conditioning circuitry must be clearly understood in order to design the best possible computer controller for the given application.
