Martin Tomlinson: Television sub-carrier transmission. Devon County Council, Hale and Dorr, April 11, 1989: US04821120 (110 worldwide citation)

In a receiver for the reception of satellite television signals sub-carrier signals carrying, for example, data are recovered from the demodulated television signal and themselves demodulated to provide data outputs. Prior to the second demodulation, each sub-carrier signal is averaged to improve it ...

Martin Tomlinson, Jonathan R Bramwell: Data communication method and apparatus. Devon County Council, Hale and Dorr, October 13, 1987: US04700363 (42 worldwide citation)

A data stream is impressed on a carrier by forming from the data stream a succession of binary symbol words which control the modulation level of the carrier during respective modulation time intervals. To generate the symbol words from the data stream, the latter is first divided into a base bit st ...
