Abstract : In the patented system the first and second carrier frequencies are generated to designate two binary states for transmitting digital information. Carrier frequencies are subdivided to generate clock frequencies at a high data bit rate. The first and second carrier frequencies are transmitted at the instantaneous bit rates determined by the clock frequencies. A frequency responsive means at a receiver detects the two different carrier frequencies and retains the resultant data bits in a storage means. The carrier frequencies are divided to sub-harmonic clock frequencies which are employed to sequentially actuate the storage means for accepting the data bits.
