摘要： A parabola generator for geometric correction of a television raster, comprises: a resettable circuit (84) for generating a repetitive ramp signal (62) and a resettable integrator (70) for generating a repetitive parabola signal (60) from said repetitive ramp signal (62). A first resetting circuit (86) initializes the ramp circuit (84) at a frequency related to a scanning frequency. An auxiliary resetting circuit (80) initializes the integrator (70) prior to integrating each repetitive ramp. The auxiliary resetting circuit (80) minimizes timing errors from variations of the ramp signal (62) due to transient conditions. In one embodiment, the scanning period is a horizontal scanning period and the ramp and parabola circuits (84,70) are reset at the end of each horizontal scanning interval. In this case, the first and auxiliary resetting circuits (86,80) are responsive to horizontal retrace pulses, for example the leading edges of the horizontal retrace pulses. A further circuit modulates the periodically reset parabolic signal at a vertical scanning rate. In another embodiment, the scanning period is a vertical scanning period and the ramp and parabola circuits (84,70) are reset at the end of each vertical scanning interval. In this case, the first and auxiliary resetting circuits (86,80) are responsive to vertical retrace pulses, for example the leading edges of the vertical retrace pulses. A further circuit modulates the periodically reset parabolic signal at a horizontal scanning rate. The parabolic waveform (60) is also reset responsive to a timing signal, rather than by allowing the minimum level of the waveform to be defined only by uncontrolled operation of an integrator.

摘要： Circuit arrangement comprising a parabolic generator (2) for supplying a periodic, substantially parabolic signal to an output terminal during the trace time and an arcuate signal generator (3) for supplying an arcuate signal, which has the shape of, for example, half a sine wave, during the retrace time. At the start of the retrace time the arcuate signal and its derivative are given values which are substantially equal to the corresponding values of the parabolic signal at the end of the trace time. The arcuate signal generator is adapted to generate the arcuate signal in a time-discrete manner under the control of switching pulses supplied by a pulse circuit (4). The pulse circuit (4) is adapted to supply such a constant number of switching pulses for generating the arcuate signal at a variable retrace time that the arcuate signal and its derivative assume values which are substantially equal to the corresponding values of the parabolic signal at the start of the trace time.

Applied to the combining stage (2, 5-8) is a sawtooth signal generated by the sawtooth generator (1) and also a sawtooth signal originating from a feedback (26) and the combining stage (2, 5-8) generates three linear combinations of these input signals. Two linear combinations are applied to the multiplying circuit (12) for obtaining a parabolic signal which is applied to a signal input terminal (20) of the amplifier (18), whereas the third linear combination is applied to the feedback input terminal (19) of the amplifier (18). The series arrangement of the deflection coil (24) and a seperating capacitor (25) is coupled to the output terminal (22) of the amplifier (18), a feedback network (26) being included between the said series network and the combining stage.
