A search stagey is useful because you can make complicated searches easily and also get reliable data.
Answer:
Quantizing error
Explanation:
In digitisation of analog signal refers to the rounding off of values which are approximately equal to the analog signals. The method of sampling chooses a few point on the analog signal and then these points are joined to round off the value to a near stabilised value. such process is known as Quantization. For any system, during its functioning, there is always a difference in the values of its input and output. The processing of the system results in an error, which is the difference of those values.
The difference between an input value and its quantized value is called a Quantization Error. A Quantizer is a logarithmic function that performs Quantization rounding off the value. An analog-to-digital converter (ADC) works as a quantizer.
The main difference between Windows and OS X is the computer you can use it with. OS X is exclusively for Apple computers, commonly known as Macs, while Windows is basically for any personal computer from any company.
