Bell and Watson extended to work on the harmonic telegraph at the insistence of Hubbard and added economic backers. During March 1875 Bell achieved with a man called Joseph Carol without the data of Hubbard. Joseph Carol was the respectable director of the Smithsonian Institution تلفن تحت شبکه voip.
He listened tightly to Bell’s ideas and offered words of encouragement. Equally Bell and Watson were sparked on by Henry’s thoughts and extended their assist sustained passion and determination. By July 1875 they noticed their purpose of making a computer device that might transmit speech electrically would shortly be realised. Their experiments had proven different hues would differ the effectiveness of an electric energy in a wire.
Today all they’d to accomplish was construct a computer device with an appropriate membrane effective at turning those hues into different electronic currents and a device to reproduce the variations and change them back in clear format at the other end. In early July, Bell unearthed that while focusing on his harmonic telegraph, he can hear an audio on the wire.
It had been the sound of a twanging clock spring. It had been on March 10th 1876 that Bell was to ultimately realize the accomplishment and communications possible of his new device. The possibilities of being able to speak down an electric cable far outweighed those of an altered telegraph system, which was basically predicated on just dots and dashes.
During the 1870’s, two well-known inventors both separately made products that might transmit sound along electrical cables. These inventors were Alexander Graham Bell and Elisha Gray. Equally products were listed at the patent company within hours of each other. There used a sour appropriate fight on the innovation of calling, which Bell eventually won.
The telegraph had been a highly effective connection system for about 30 decades before Bell started experimenting. The key problem with the telegraph was so it used Morse signal, and was limited to giving and getting one concept at a time. Bell had a good understanding about the nature of sound and music.
That enabled him to understand the possibility of sending several concept along the same cable at one time. Bell’s thought wasn’t new, others before him had envisaged a numerous telegraph. Bell offered his own solution, the “Harmonic Telegraph” ;.This was based on the key that musical records might be delivered simultaneously down the same cable, if those records differed in pitch.
