must reinsert the nontransmitted carrier before successful heterodyning can take place. Radio has become a sophisticated and complex area of electrical engineering, especially when compared to its elementary origin. Every day new radio applications are being found, ranging from digital radio-controlled garage-door openers to weather satellites and from tracking systems for polar bear migrations to radio telescope investigations of the universe. This multiplicity of uses demonstrates the important part radio plays in the world today.
