Noise-shaping and sigma-delta converters 1.1 INTRODUCTION It is observed that most physical quantities in nature are analog signals. These quantities include: temperature‚ pressure and speed—to mention a few. Further‚ these quantities assume an infinite number of possible values other than 1’s and 0’s. Understandably‚ these analog quantities must be converted into binary strings‚ representative of their values. The process of conversion of analog signals into their equivalent digital form is termed analog-to-digital

All children are unique and develop at their own rate but they tend to follow a similar pattern.

Moral development is usually adapted from the setting a child lives and would usually deem something wrong and right‚ based on what their parents believe is

shown on the graph show that there is a strong positive correlation between the average rate of conductivity and the surface area: volume ratio. As the surface area of the Agar cube increases‚ the rate of conductivity will steadily increase‚ too. The trend line of the graph shows as an exponential graph because at one point there will be no more conductivity due to too small or too big Agar cubes. A difference can be seen in the average rate of conductivity depending on surface area because the Agar
