ABSTRACT:
A code generator which produces a transmission code in response to a serial binary data stream applied to its input. The transmission code is similar to that know as WAL2 but whereas WAL2 involves a double frequency component when the binary data changes from `1` to `0` or vice versa the transmission code produced by the code generator holds the output signal constant at a level intermediate those corresponding to the binary `1` and `0`. This reduces the high frequency content of the transmitted signal and consequently reduces crosstalk between the channels. The code generator includes a first current source which is connected to a summing network through a first switch, a second current source which is connected to the summing network through a second switch and a control circuit which produces signals on lines to selectively operate the first and second switches.
