How did Edward Howard Armstrong die?
Which was first AM or FM?
This type of transmission is called amplitude modulation (AM). It appears to have first been thought of by John Stone Stone in 1892. Many years after Armstrong’s invention of the super heterodyne, he solved radio’s last major problem, static, by inventing frequency modulation (FM), which he successfully tested in 1933.
What is the main reason for the decline in radio usage?
The decline in radio listenership was also found to be due to repetitive music, changes in format, the increase in streaming service opinions and a lack of enjoyment or ability to find preferred content.
What did Armstrong built behind his house?
While still a boy, Armstrong set about becoming an inventor. His homemade radio equipment eventually filled his bedroom, and during high school, he built a 125-foot tall radio antenna on the lawn of his house.
