ABSTRACT
Facsimile telegraphy is a technique to send printed messages such as typed or hand written from one station to another. The word “Facsimile” means “exact reproduction”. In facsimile transmission, an exact reproduction of the picture or document is provided at the receiving end. Fax, short for facsimile transmission is a way of sending text of pictures over telephone lines. A fax is a machine that can transmit photographs, written documents, etc. The most common example is news paper printing. News, photographs, reports available at one place can be sent to other place to be published in the next morning edition. FAX machines provide an easy way to send documents to any phone number equipped with another fax machine. A fax machine works by scanning each outgoing page, converting the image into a series of light and dark dots. The signal obtained from scanning cannot be directly transmitted, as it is difficult to amplify low frequencies.
