855 Digital To Analogue Conversion

Figure 8.14 shows the basic principle of a digital to analogue converter. The power sources of 8 V, 4 V, 2 V, and 1 V are represented by the small circles. When a binary code is presented at the input, with the most significant bit (MSB) at the 8 V end and the LSB at the 1 V end, the switches are operated electronically. In

the diagram binary 1100 (12) is placed at the inputs. This means that the two inputs of 1 will switch their respective voltages of 8 V and 4 V to the output lines, and the electronic summing circuit will add them together to give a 12 V output.
