Document Type and Number:
Japanese Patent JPS53128930
Kind Code:
A
Abstract:
A circuit for producing a periodic parabolic signal by means of squaring a sawtooth-shaped signal, for example for controlling an east-west modulator in color television receivers, a parabolic disturbance occurring during the retrace period being reduced by means of a transistor amplifier operating as an emitter follower during the trace period and as a switch during the retrace period.
