AM and FM in radio broadcasting

Abstract

In partial fulfillment of the requirements for a master's degree in Physics at Boston University, I have written a thesis on the production and modulation of radio waves. Part I of this thesis is written especially for those not well versed in science. It is therefore, written in semi-technical, non-mathematical language. I have begun the discussion of transmission of messages between points more or less distant by describing how a simple mechanical telephone system may be had by connecting the bottoms of two tin cans by means of a string. This is followed by a description of the method by which sound waves are converted into electric currents as in the electric telephone.
