What is monotonicity?

The

digital converter to analog (DAC or D-A-A) is a device that converts the digital code to an analog signal. The transfer can be done vice versa using an analog digital converter (ADC). In both devices are two of the key specifications of linearity and monotonicity. Technological restrictions prevents DACS and ADC in ideal. Montonita is one measure that helps describe how well they work. In general, monotonic DAC is not valuable. Some mathematical functions, called the monotonous mathematical functions , keep the same order between X and Y, on the one hand or consistently reverse the order. The result of two options: Either X and Y increases or remain the same or x and y drop or remain the same.

In electronics is a monotonous DAC at which the analog output monitors the direction of the digital input, no matter how much the thdigital input differs. In other words, the analog output increases consistently with increasing input and decreases with decreasing input. If an analog output had no everKoli follow the direction of digital input-decreases when it increases or increases when decreased-then DAC was considered mononotonic. When it comes to monotonicity, there is nothing like a degree.

Linearity - a link to an ideal output that would look like a straight line - related to monotony. The ideal change for one step is 1 LSB (the least significant bit). The missing code is marked -1LSB. In order to guarantee a monotonous reaction, there must be a differential non -linearity error (DNL), a rate of difference between the ideal output and the actual output for the following steps, the rate of accuracy, less than 1 LSB. This meant to be up to, but without including, ± 1 lsb. According to some, however, it is only for the warranty and it is possible for the smuggler to be monotonous and have a DNL that will reach a maximum or more than 1 LSB.
