Armstrong presented his newest finding to a group of RCA officials in 1934 he later displayed the power of the technology using an antenna at the top of the Empire State Building.

Scientists at the Radio Corporation of America (RCA) were also examining frequency modulation techniques to improve radio transmissions.

For the second time, Armstrong was not the only one experimenting with such technology.

On December 26, 1933, he received US patent 1,342,885 for a “Method of Receiving High-Frequency Oscillations Radio” for his FM technology.

Armstrong administered his experiments in the basement of Columbia University’s Philosophy Hall.

Earlier to this, amplitude modulation (AM) radio had been hugely susceptible to such interference, which was what urged Armstrong to investigate the problem in the first place.

This invention improved the audio signal of the radio by managing the static caused by electrical equipment and the earth’s atmosphere.

Armstrong is most widely known for inventing frequency modulation, or the FM radio, in 1933.

This was his first experience with the legal system that would later cause him so much turmoil.

Although an initial case was settled in Armstrong’s favor, a later decision ordered that De Forest was the true inventor of the regenerative circuit.De Forest believed that he was the first to develop the regenerative circuit, as did many other inventors who became involved in the legal dispute that lasted many years. However, the following year, another inventor, Lee de Forest, filed several applications for competing patents.On October 6, 1914, Armstrong was awarded a patent for this invention.Regeneration amplification worked by feeding a received radio signal by a radio tube 20,000 times per second, increasing the power of the received radio signal, and allowing radio broadcasts to have a bigger range.

The same year he graduated, he invented his first major invention, the regenerative or feedback circuit.He graduated from Columbia in 1913 with a degree in electrical engineering.Armstrong made a strong impression on several of his professors.His interest in science and technology took Armstrong to Columbia University in New York, where he studied at the school’s Hartley Laboratories, a separate research unit at Columbia.He began studying radio and building homemade wireless equipment, including a 125-foot antenna in his parents’ backyard. The young Armstrong was captivated by it.

Armstrong was only 11 when Guglielmo Marconi sent the very first wireless message across the Atlantic Ocean.

Vitus’ Dance-a muscular disorder-which forced him to be homeschooled for two years.

At the age of 8, Armstrong became afflicted with St.

Both of his parents were deeply involved in the Presbyterian Church.

His father was an employee of Oxford University Press which published a variety of books such as Bibles and classical works, while his mother was a public school teacher.

He was the eldest of three children of John and Emily Armstrong.

Armstrong was born in New York City on December 18, 1890.
