CS263452B1 - Secam-pal system decoder - Google Patents

Abstract

The solution is in the field of color television and can. to be used in a two-standard color television and color video control instruments. The goal of the solution is increasing signal resolution stability PAL. The device has a signal amplifier color block colorful synohronizaoe system SECAM, color switch, symmetrical tilting circuit, comparator frequency generator PAL and flip-flop circuit from PAL to SECAM and vice versa. The new one in the device is that it does the flip-flop is connected to the switch input SECAM-PAL modes generator Intermediate Frequency Via Detector Impulse peaks.

-4 OBJECT OF THE INVENTION The SECAM-PAL decoder according to the author's guide. Characterized in that a pulse peak detector and an additional key circuit are introduced in order to increase the resolution of the PAL signal resolution, wherein the flip-flop output is coupled to an input of the PAL comparator with the pulse decoder, and the output of the comparative intermediate frequency generator of the PAL system is connected to the power terminal via an additional key whose control input is connected to the flip-flop output · 263452
