Often a supply of great confusion, determining productivity rate and efficiency is nowhere close to as difficult as it might seem. The discovery that electromagnetic waves are capable of transmitting information sparked the invention of radio. The technology scaled like the old inventions in the telegraph as well as the telephone. According to some researchers, the amplitude modulation technique originated in the experimental and theoretical work of Leblanc, in 1886, Mayer (1875) and Rayleigh (1894). For example, the very first successful attempt to transmit audio signals over telephone lines happened inside mid-1870s and this may be called one of the first transmissions happening by using some type of amplitude modulation.
