Sand Castle Pulse Generator Circuit of Image Display Equipment

摘要

The disclosed sand castle pulse generation circuit is a decoder in which the output terminals of horizontal and vertical blanking pulses and clamping pulses of video signals received by video display devices such as television receivers are separated into audio signals, color signals, and synchronization signals. If not provided to the outside to generate a sand castle pulse at the same time to adjust the pulse width.;The sand castle pulse generating circuit of the image display device according to the present invention is a video display device having a decoder without an output terminal of a horizontal and vertical blanking pulse and a clamping pulse of an image signal received through a tuner. The clamping pulse generating circuit unit which the operator adjusts the duty according to the horizontal blanking pulse included in the video signal received by the video display device and generates the clamping pulse according to the adjusted duty, and the horizontal / The sand castle pulse is mixed by mixing the horizontal and vertical blanking pulse mixing circuit unit which outputs the mixed blanking pulse by mixing the vertical blanking pulse, and the clamping pulse and the mixed blanking pulse output from the clamping pulse generating circuit unit and the horizontal / vertical blanking pulse mixing circuit unit, respectively. It is comprised by the sand castle pulse generation circuit part which outputs.;Therefore, the present invention provides a very wide range of utilization when selecting a decoder, and the width of the sand castle pulse can be adjusted, thus providing an effect of facilitating product development.
