video logic is a high speed digital logic processing module with multiple boolean and inversion functions. it is capable of logical combinations of video rate signals throughout the video bandwidth. each of
the eight inputs includes a high speed comparator which converts any input signal into key logic around a threshold of 0.5 volts. as with all modules in the lzx visionary line, the inputs can therefore
receive any type of signal — not just binary logic pulses.
there are two boolean functional blocks with 3 inputs and 3 outputs each. the outputs represent the logical and, or and xor combinations of the 3 inputs signals. additionally, there are two inverter
functions. the output of these inverters represents the logical inversion of the input signal. through patching some signals to the inverters before the boolean functions, nand, nor and xnor logic functions
are made possible.
