Solution
-
Hold – the action of holding the voltage for a brief amount of time by use of a capacitor. TRUE. This is a common step in the ADC process, where the input voltage is held constant to allow for accurate measurement.
-
n represents the number of bits in the digital value of the conversion. TRUE. The number of bits, often represented by 'n', determines the resolution of the ADC.
-
The smaller the n, the closer the digital value is to the actual analog voltage. FALSE. The larger the 'n', the higher the resolution of the ADC, and the closer the digital value is to the actual analog voltage.
-
Analog-to-Digital Converter (ADC or A2D) – a circuit that takes in an analog voltage and produces a digital representation of its value. TRUE. This is the basic definition of an ADC.
-
Sample – the action of duplicating the voltage value of the input signal. FALSE. Sampling is the process of converting a continuous time signal into a discrete time signal, not duplicating the voltage value.
-
The number of bits n is called the ADC’s accuracy. FALSE. The number of bits 'n' is referred to as the ADC's resolution, not its accuracy.
-
Digitizing, quantizing, or discretizing is to convert the analog voltage into a digital number. TRUE. These terms refer to the process of converting a continuous analog signal into a discrete digital signal.

A: An Arduino uno board has a 10-bit ADC attached to its analog input pins. Every analog input voltage is converted into a digital number bythe ADC which is attached to the board. If the analog pin is connected to a light-dependent resistor and a fixed resistor combination and theoutput voltage provided by the combination is 2.75V. If the Arduino board is working at a 5V supply, then find the 10-bit digital codecorresponding to the given input voltage. (Just write the 10-bit digital number)Output =
