Question

A sensor converts the influx of light linearly to digital code through voltage changes. The sensor has a voltage range of 0-5 V and the maximum number of codes that it can quantize the voltage change is 2048. The bit-size of the quantizer is ............................. (In integers).

Hint:

The number of bits in a quantizer is determined by the formula $\text{Bit-size} = \log_2(\text{Number of quantization levels})$.

Answer 1

The number of quantization levels is given by $2048$. The bit-size of the quantizer is the number of bits needed to represent these levels. This can be calculated as: \[ \text{Bit-size} = \log_2(2048) = 11. \]
