The system receives two CVBS signals by two SAA7111 decoder chips. Under the control of the FPGA, the two-waysignal is synthesized to one way and transmitted to the ARM11 module.
The symmetric ternary current-mode CMOS circuits designed by using this theory not only have simpler circuit structures and correct logic functions, but also can process two-waysignal.
