Document Type and Number:
Japanese Patent JP2545071
Kind Code:
B2
Abstract:
A circuit arrangement for generating a sawtooth-shaped signal for the field deflection in a picture display device with an amplitude which is substantially independent of the field frequency is disclosed. The value of the sawtooth-shaped signal during the occurrence of a sampling pulse is compared with a reference value for generating a control signal controlling the slope of the sawtooth-shaped signal. To eliminate instability in amplitude, which might result from phase jitter of the incoming field synchronizing signal and might cause an interlace error, sampling pulses are applied whose repetition frequency is substantially equal to the nth part of the field frequency, where n is an integer which is larger than 1, preferably a small multiple of 2.
