6. The Digital Revolution in Telecommunications
April 20, 2023
In the old-style analog telephone system, voltage increased and decreased across the wires, corresponding to the human voice signal. But in a digital system, that all changes. Learn how the human voice is changed into binary values, sent over the system, and then converted back into volts with the voltage applied to the speaker in the phone handset. The human ear takes it from there.
5. First Connections: The Telephone Network
April 20, 2023
In the 1870s, Alexander Graham Bell was trying to improve the telegraph when he and his assistant discovered that speech itself could be transmitted over telegraph wires. Explore the subsequent engineering developments that brought the telephone to almost all households, including Bell
