Title: Frequency division with non- integral division ratio
IPC: H03K23/00
Filed: 1978-11-21
Abstract: Division by non integral ratios is often required for carrier generation in communications systems. Such division - i.e. multiplication by Z/N < 1 (e.g. 11/62) is commonly effected by dividing by N and using the Zth harmonic of the resultant output. As the harmonic content decreases with increasing Z, the invention aims to increase the desired harmonic component, so as to reduce the requirements for subsequent filtering. Thus a frequency divider is employed and its division ratio is varied in suitable manner during N input periods; limitations are also imposed on the symmetry of the output waveform. The output waveform can be so arranged as to make its frequency spectrum rich in the desired harmonic, whilst reducing the adjacent, unwanted harmonics. A divider apparatus is also proposed, with a programmable divider (R, LS) and gate (A) which receives the input pulses and drives an output flip-flop (H) and counter means (T1, T2) which produce control signals (SI, SII) with which the divider is programmed. The divider may, for example, count 21 DIVIDED 2, 3 and 31 DIVIDED 2 impulses. <IMAGE>

Title: Data Processing Apparatus
IPC: G06F9/445
Filed: 1978-11-22
Abstract: The present invention relates to data processing apparatus having an auxiliary processor to execute selective system reset functions in order to overcome the problems of executing system reset via the normal data processing linkages when defective units occur in the linkages or when units are reserved. Both simplex and multiplex processor systems are considered, but the significant embodiment comprises one control processor 80, one attached auxiliary processor 82, one attached channel 84 and the OPOUT and SUPPOUT lines 86 and 87 to a peripheral unit. The auxiliary processor connects to the channel via path 83 and to the OPOUT and SUPPOUT lines via path 85. When a reset instruction is decoded in processor 80, the decoder signals processor 82 which applies I/O RESET signals to the channel and INHIBIT signals to line 85. The inhibit signals suppress lines 86 and 87 for a time period sufficient to indicate system reset to an attached peripheral unit. With multiple channels and hence multiple lines 83 and 85, processor 82 includes a line selection decode (104) responsive to instruction based target data and latches (120) indicating the availability of the target. <IMAGE>

Title: Recording/reproducing system
IPC: G11B20/22
Filed: 1978-11-30
Abstract: In a method of recording and/or reproducing an analog signal using a sensor 5, 6 and a recording medium which is movable relative to the sensor, a sampling signal S9 is generated 10 which has a frequency which is variable dependent upon the amount of wow and flutter caused by fluctuations in the speed of the relative motion. A reproduced signal S5 is sampled 11 by means of the sampling signal and a sampled signal is stored in a memory 14. The stored contents of the memory are read out by using a reading signal S15 with a predetermined frequency, thereby to remove from the reproduced signal varying frequency components caused by the wow and flutter. <IMAGE>

Abstract: A transistor horizontal deflection circuit (40) is energised from a source (10) of unregulated direct voltage derived from the power mains but is d.c. isolated therefrom. A switching voltage regulator (26) couples the direct source to the horizontal deflection circuit (40). The regulator includes a controllable switch (28) serially coupled with the primary winding (24a) of a transformer (24) and the source. The switch is controlled by the output of a transistor (77) in a control circuit (68) responsive to an energy sensor (38) to maintain a constant voltage or energy level in the horizontal deflection circuit (40). A secondary winding (24d) conductively isolated from the primary winding (24a) is coupled across the deflection winding (50) for forming a path for bidirectional current flow. The horizontal output transistor (44) is coupled in parallel with the deflection winding (50) for producing retrace pulses which are coupled to the primary winding (24a) for reducing the current in the controllable switch (28) to zero during the retrace interval, thereby turning it off. <IMAGE>
