Smartphones connect to the internet wirelessly. When you send a text from your phone, the phone must first convert the information in the text into radio waves. The phone then sends these radio waves wirelessly to a nearby receiver that is connected to the internet. Describe the analog/digital conversion that occurs when you send a text. Be sure to include the definitions of both terms. Please make it detailed !!!
Analog and digital are two types of signals that are used to transmit information. Analog signals are continuous waveforms that represent continuous variations in physical quantities such as voltage or frequency. Digital signals, on the other hand, are discrete signals that represent information in the form of a sequence of discrete values (usually represented by binary numbers).
When you send a text from your phone, the phone must first convert the information in the text into digital signals. This process involves encoding the text into binary code, which consists of a series of 1s and 0s. Each character in the text is assigned a unique code that represents it in binary form. For example, the letter "A" may be represented by the binary code 01000001.
Once the text has been converted into digital signals, the phone then converts these digital signals into analog signals. This is done by modulating the digital signals onto a carrier wave, which is a continuous sine wave with a specific frequency. This modulation process involves varying the amplitude, frequency, or phase of the carrier wave according to the digital signal that is being transmitted. This results in the creation of radio waves that carry the digital information in analog form.
The phone then transmits these radio waves wirelessly to a nearby receiver that is connected to the internet. The receiver then demodulates the radio waves to extract the digital information that was modulated onto the carrier wave. The digital information is then decoded back into text so that the recipient can read the message.
In summary, when you send a text from your phone, the information in the text is first converted into digital signals, which are then modulated onto a carrier wave to create radio waves. These radio waves are transmitted wirelessly to a receiver, which demodulates the radio waves to extract the digital information that was originally sent as text. This process of converting information between analog and digital forms is crucial for transmitting information wirelessly over the internet.
