摘要：A digital signal recording system carries out the operational steps of gatingrespectively sawtooth waves in response to two digital signals of a pulse train of constantperiod and data pulses constituted by the presence or absence of pulses in accordancewith data, mixing the sawtooth waves thus gated, and recording the waves thus mixed as acomposite sawtooth wave on a recording medium. The positions of rise and fall of thecomposite sawtooth wave respectively correspond to the above mentioned two digitalsignals. A digital signal reproducing system carries out the steps of reproducing signalsrecorded by the above described recording system, separating the pulses of constantperios and the data pulses through the utilization of the characteristics of the signalpulses thus reproduced, and deriving two digital signals.
