Question:medium

Increasing the resolution of an ideal N-bit ADC at constant reference voltage will:

Show Hint

Each additional bit added to an ADC cuts its quantization step size in half. Since noise power is proportional to the square of the step size (\(\Delta^2/12\)), every extra bit reduces the quantization noise power by a factor of 4 (\(6\text{ dB}\) SNR improvement).
