A: If the signal is analogue then an ADC analogue to converter is required. The output will be in a digital form and that can be decoded and displayed as readout using LEDS or any other visual media

I think you mean 'SCANNER'. But, whatever! :)) It means: A device that converts a printed image (as text or photograph) into a form a computer can use. (As for displaying on the screen.)
When you send a text message, the signal travels from your device to a nearby cell tower, which then relays it to a mobile switching center. From there, the message is routed through the network to reach the recipient's mobile carrier. Finally, it is sent to the recipient's cell tower and delivered to their device. Throughout this process, the message is often converted into digital data packets for efficient transmission.
an image scanner(scanner) is a device that optically scans images, printed text, handwriting, or an object, and converts it to a digital image. A printer is a peripheral which produces a text and/or graphics of documents stored in electronic form, usually on physical print media such as paper or transparencies.
A keyboard is the most commonly used tool for entering text into digital devices.
A scanner takes an input which is printed materials (pictures, text) and converts it to an electronic format that can be edited.
A printer is a device that produces soft copies of digital documents by transferring text and images from a computer onto paper.
An image scanner optically scans images, printed text or handwriting and converts it to a digital image. It was invented by Ray Kurzweil.
