The switched-mode field-scanning circuit makes use of a load constituted by a vertical deflector, a measuring resistor and a connecting capacitor. The load is connected to the output of a circuit which generates a sawtooth signal by means of the line-scanning retrace signal and has a single unidirectional-voltage, bi-directional-current channel. The switched-mode field-scanning circuit is intended for use in transistorized video-frequency receivers. |
