Although the two systems require about the same transmitter power (within 1 dB) to provide rms output signal-to-noise (S/N) ratios between 20 and 30 dB at threshold, the analog system is generally simpler, whereas the digital system is capable of greater accuracy. However, the digital ...
We often need to measure signals that vary; these are called analog signals. A 5V analog sensor may output 0.01V or 4.99V or anything inbetween. Luckily, nearly all microcontrollers have a device built into them that allows us to convert these voltages into values that we can use in a pr...
(PWM) technology,PLC transistor digital output signal was controlled by controlling the duty ratio of the pulse.By applying smooth circuit,the linearity of the output analog signal was improred.The functionality of the PLC transistor digital output was widened.The research shows that the method ...
The disclosed encoder is adapted to produce both digital and analog output signals corresponding to the angular position of a rotary shaft, or the position of any other movable member. The digital signals comprise a series of binary signals constituting a multi-digit code word which defines the ...
In the general case of a digital-to-analog R-2R ladder network converter, the expression of the output voltage depends on the digital code that can be found on the input and also on the reference voltage: vS=Eref∑j=1nan‐j2j The coefficients a(n-j) can only assume the values “0...

Digital potentiometers allow you to adjust an analog voltage, while DACs adjust current, voltage, or both. Potentiometers have three analog connections: the high connection, the wiper (or analog output), and a low connection (Figure 1a). DACs operate quite similarly, but not identically....
