Abstract: A method for communicating binary data using modified frequency shift keying techniques generally includes the steps of selecting a first bit count representative of a first untranslated frequency denoting a data signal at a first logic state, selecting a second bit count representative of a second untranslated frequency denoting a data signal at a second logic state and computing a mean bit count intermediate the first and second bit counts.A signal is detected which has a first component at a first translated frequency and a second component at a second translated frequency and defines a first interval of time having boundaries identifiable as T0 and T1, a second interval of time having boundaries identifiable as T1 and T2, a third interval of time having boundaries identifiable as T2 and T3 and a fourth interval of time having boundaries identifiable as T3 and T4.
