The process of converting analog signals into digital signals so that they can be processed by a receiving computer is referred to as:Answer: D. Digitizing
Explanation:To provide a detailed solution, let's break down the process of converting analog signals into digital signals and explain each step:
1. Analog Signals:- Analog signals are continuous waveforms that represent real-world data such as sound, temperature, or light intensity.
- These signals have infinite possibilities and can take any value within a specific range.
2. Digital Signals:- Digital signals are discrete and binary in nature, consisting of only two possible values: 0 and 1.
- These signals are used by computers and digital devices to represent and process information.
3. Process of Conversion:- The process of converting analog signals into digital signals involves several steps:
a. Sampling:- The analog signal is sampled at regular intervals to capture its amplitude at each point in time.
- The sampling rate determines the number of samples taken per second, also known as the sample rate.
b. Quantization:- Each sampled value is quantized by assigning it a specific digital value from a predefined range.
- This process reduces the infinite possibilities of the analog signal to a finite number of digital values.
- The number of digital values available is determined by the bit depth or resolution.
c. Encoding:- The quantized digital values are encoded into binary code, usually represented as a series of 0s and 1s.
- This encoding allows the digital signal to be transmitted or stored in a format that computers can process.
d. Transmission:- The digital signal can now be transmitted over various communication channels such as cables, fiber optics, or wireless networks.
- The binary representation of the signal ensures accurate and reliable transmission.
e. Reception and Decoding:- The receiving computer or device receives the digital signal and decodes it back into quantized values.
- The decoding process reverses the encoding and quantization steps, reconstructing the original analog signal.
f. Processing:- Once the analog signal is converted back to digital form, the receiving computer can process it using various algorithms and techniques.
- Digital signal processing (DSP) techniques can be applied to manipulate, analyze, or extract information from the digital signal.
Conclusion:- The entire process of converting analog signals into digital signals, including sampling, quantization, encoding, transmission, reception, decoding, and processing, is collectively known as digitizing.
- Therefore, the correct answer to the given question is D. Digitizing.
