ABSTRACT:
An improved binary signal discrimination system for demodulating FSK transmitted signals is disclosed which requires that both the mark or binary "1" signal frequency and the complementary of the space or binary "0" frequency be present for a mark signal to be recognized; and, conversely requires that both the space signal frequency and the complement of the mark signal frequency be present for a space signal to be recognized.
