Question

Assuming that a 4-bit ADC channel accepts analog input ranging from 0 to 10 V, determine the following:

Number of quantization levels

Answer 1

A 4-bit ADC has 16 quantization levels, with each level corresponding to an increment of approximately 0.625 volts in the 0 to 10 V input range.

Step-by-step explanation:

When discussing a 4-bit ADC (Analog to Digital Converter), the concept of quantization levels is crucial. The number of quantization levels available in an ADC is determined by its bit size. In this case, a 4-bit ADC can represent 24 or 16 different levels. These levels are the smallest increments of voltage that can be distinguished by the ADC. Since the range of input voltage is from 0 to 10 V, each quantization level represents a voltage increment of 10 V divided by 16 levels, which is approximately 0.625 volts per level.
