9.1 Introduction Connecting digital circuitry to sen devices are inherently digital encoders are easily interfaced with of their signals. However, when analog devices are more complex. What is needed is a way to electr digital (binary) quantities, and vice or ADC, performs the former task DAC, performs the latter.

to DAC nsor devices is simple if the sensor themselves. Switches, relays, andh gate circuits due to the on/off nature e involved, interfacing becomes much ronically translate analog signals intoe versa. An analog-to-digital converter, while a digital-to-analog converter, or 3
