This post will be determining what objects and concepts are either digital or analog from what was learned in class so far.
Early satellites started off as analog and went to digital as they got smaller. They primarily transmitted signals using continuous wave radio frequencies.
Hieroglyphs began as analog and became digital through fixed numbers or sounds as techonolgy advanced. They began by visually representing objects, sounds and ideas and later became digital into computer-readable numbers.
The first telegraph was digital as it worked by sending electrical pulses rather than continuous waves. Each pulse represented a specific unit of information. Which was considered morse code, which were dots and dashes. These dots and dashes allowed for information to be sent over a device for others to understand as each code made a letter.
The telephone is analog as it sends a pressure wave through some sort of median such as a wire or air. It used continuous electrical signals and were not pulses. The microphone in Alexander Graham Bell’s early telephone took pressure and translated it into electrical signals, which were then converted into sound at the reciever.
