Abstract :
Among the family of pulse time modulation (PTM) techniques, square wave frequency modulation (SWFM) is particularly well suited to the transmission of high-quality wideband instrumentation and video signals such as MAC and high definition TV over optical fibres due to its attractive combination of performance and simplicity. This paper discusses aspects of SWFM and describes two experimental systems employing novel demodulators suitable for 5.5 MHz (PAL) and 12 MHz wide format MAC bandwidth systems respectively
