Question

The measured values of a sensor must first be processed by which of the following prior to sending

to a computer?
A. an ADC
B. a DAC
Ca CPU
D. a PLD​

Answer 1

The measured values of a sensor are processed by an Analog-to-Digital Converter (ADC) before being sent to a computer, as sensors produce analog signals which need to be converted to digital format that computers can process.

Step-by-step explanation:

The measured values of a sensor must first be processed by an Analog-to-Digital Converter (ADC) prior to being sent to a computer. Sensors typically produce analog signals that represent physical quantities such as temperature, pressure, or light intensity. Before a computer can process these signals, they must be converted into a digital format, which is where the ADC comes into play. This device takes the analog input from the sensor and converts it into a digital signal that the computer can understand and process.

Other options like a Digital-to-Analog Converter (DAC), a Central Processing Unit (CPU), or a Programmable Logic Device (PLD) serve different purposes. A DAC converts digital signals to analog, a CPU processes digital information, and a PLD is used in reconfigurable digital circuits but is not specifically tasked with converting sensor data for a computer.

Answer 2

A. an ADC

Step-by-step explanation:

A sensor can be defined as a device designed to detect changes or events within its immediate surroundings and then transfers this data to the central processing unit of a computer.

Simply stated, a sensor is an input device that detects changes in its environment and sends the data to another electronic device. Thus, this data must be converted by an analog to digital converter (ADC) into a digital format that is understandable by the central processing unit (CPU) of a computer.

Hence, the measured values of a sensor must first be processed by the analog to digital converter (ADC) prior to sending to a computer.

Some examples of sensors are light sensors, tactile sensors, metal sensors (detector), etc.
