To the non-technical reader the transmission of speech and music with no visible means of intercommunication is somewhat of a mystery. While it is mysterious it is no more mysterious than the production and recognition of light, for radio and light waves are of exactly the same nature. The relation of radio and light waves is the same as that existing between red and blue light, it is merely a matter of frequency. Of course the colors of the radio spectrum are invisible as far as the human eye is concerned and the radio receiver is nothing more than an artificial eye sensitive to these extremely low-frequency colors.This little volume has a three-fold purpose: first, to present in simplified form a brief discussion of what happens when messages are sent and received by radio- secondly a brief, simplified description of the apparatus required to produce these effects and how it operates- and lastly, practical unbiased information for the experimenter who desires certain results but who does not know what apparatus is necessary.The use of mathematics has been almost entirely avoided and the treatment in most cases is qualitative rather than quantitative.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
