Title: Methods of and apparatus for encoding and recovering binary digital signals
IPC: G11B20/10
Filed: 1977-07-11
Abstract: In this method, which can be used, in particular, in transmission systems and in magnetic storage and recovery systems for digital data, for example three bits in each case (three time intervals T) of a binary data signal are combined to form one word. This word corresponds to data cells of the transmission or recording signal. A data cell (Z) exhibits six possible points of signal change (P1 to P6). The binary data signal is converted into a transmission or recording signal in such a manner that a minimum distance (3/2 T) and a maximum distance (6 T) is always ensured so that self-clocking is possible during the reading. Since it is not sufficient only to pay attention to the signal changes within one data cell (Z) but care must also be taken that two signal changes (P5 and P1) of adjacent data cells (e.g. Z4 and Z5) are not closer together than the required minimum distance (3/2 T), the present word is in each case compared with the preceding and following word. If it is found for a word, that a signal change should take place at a point (P5) which is not the minimum distance (3/2 T) away from the point at which a signal change (P1) for another word should take place, the two signal changes are combined at one point (P6). For this purpose, the device for carrying out the method has a coding device with three coders (17, 24, 29) for the present, preceding and following word and switching means (33) which provide a signal change at the boundary (P6) between the data cells (Z4, Z5) instead of the two prevented signal changes (P1, P5). <IMAGE>

Abstract: 867,526. Transistor pulse shaping circuits. INTERNATIONAL COMPUTERS & TABULATORS Ltd. Aug. 29, 1958 [Sept. 16, 1957], .No. 29063/57. Class 40(6) A pulse shaping circuit comprises a transistor to the collector electrode of which is connected a source of clock pulses acting as power supply for the transistor through the primary winding of a transformer, the pulses to be reconstituted being applied to the base or emitter electrode of the transistor with such polarity as to cause the transistor to conduct when a clock pulse is applied simultaneously thereto, the resulting flow of collector current producing an output pulse in the secondary winding of the transformer. Negative-going clock pulses are applied to terminal 9 and thence through the primary winding, 6 to the collector electrode of the transistor. Input pulses, in the circuit shown, are negative-going and are applied from a source 10 to the base of the transistor. Upon the simultaneous application of pulses to the collector and base, collector current flows to induce a voltage in output winding 7 and also in feedback winding 8 to apply positive feedback to the emitter electrode and increase conduction through the transistor. Upon the termination of the clock pulse, conduction in the transistor ceases; a diode 16 in series with a currentlimiting resistor 15 damps out the overshoot in the output circuit. The feedback winding 8 may be omitted, Fig. 2 (not shown); in this case feedback may be provided by a connection through a diode from the output circuit to the emitter electrode thus maintaining output for the full clock pulse duration even when the input pulse is shorter than the clock pulse. The circuit may be modified for the application of positive-going input pulses from a low impedance source to the emitter electrode; the feedback winding 8 is then taken to the base electrode which is also connected through a resistor to a positive bias voltage.
