    Abstract: PROBLEM TO BE SOLVED: To generate a clock signal synchronized with receiving data at a high speed in a data receiver. SOLUTION: This method generates a clock signal SCLK substantially synchronized with receiving data which is used in a data receiver 6. Receiving data is provided with a synchronous word that has a prescribed frequency ftx and a prescribed value. This method generates n clocks (CLK1 to 8) which virtually has a frequency fclk of the prescribed data frequency ftx and also whose phase is deviated by 1/n clock cycle from an adjacent clock (A), uses each of n clocks, samples the synchronous word and also decides which one optimally synchronizes with the synchronous word among n clocks (B) and is also provided with each stage that offers a prescribed one among n clocks which offers the clock signal SCLK to an output 18 (C).

    Abstract: A timebase circuit is described, for compensation of picture dimensions of television type display, for EHT fluctuations in which a control current (ic) is derived by multiplying (17) a current (IEHT) dependent upon the picture beam current with a reference current (IDAC) derived from a digital to analogue converter (19) fed with a digital code.

    Abstract: @ A timebase circuit for use in the vertical timebase of a television receiver in which a linearity control current fed to the ramp capacitor is derived by multiplying a current proportional to the difference between the instantaneous and average ramp voltages by a reference current which may be adjusted to control linearity.

    Abstract: A television deflection system failure detection circuit is described in which a first latch (8) is set during a first portion of the frame period and is reset by a fly-back signal the output of the latch being gated by a gating circuit (17, 19-21) to set a reset or output latch (18) during a second portion of the frame period which does not overlap the first portion, and in dependence upon the state of the first latch (8).
