4. FAX System (Overview)
A FAX (abbreviation of facsimile) is a device that sends and receives image data using either an analog
or a digital telephone line. The following describes the analog line system (For G3, see 6. FAX
Standards).
The three basic units of a FAX are the scanner (for reading the image), the control circuit, and the
printer.
The scanner splits the image into a fine grid, then reads the brightness (white/black) of each cell. This
operation is called scanning. The white/black information is converted to a digital signal: bright cells
become 1, dark cells 0.
The digital signal from a scanned image is subjected to DA conversion (modulation) by the control
circuit to enable transmission over an analog telephone line. After conversion, the data is sent as an
analog signal. The sound audible during transmission is image data that has become an analog signal,
that is, an audio signal.
The analog signal arriving over the telephone line is then subjected to AD conversion (demodulation)
by the control circuit of the receiving FAX machine, and restored to a digital signal.
The black/white information obtained from the AD conversion is sent to the printer, where black cells
are reproduced on the paper at the positions where they were on the original.
