logic operations for shape and key combinations, switch controller, quantization
Video Flip Flops is a high speed digital logic processing module with four single bit digital memory functions. It is capable of processing signals throughout the video bandwidth. Each of the ten 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 identical channels arranged in columns. Each column contains two flip flops. The first flipflop is a toggle flipflop with Toggle, Set, and Reset inputs. A positive pulse on the Set input will switch the output high. A positive pulse on the Reset input will switch the output low. A positive pulse (or button press) on the toggle input will invert the current value of the output. Below the toggle flipflop is a data flipflop. The data flipflop will transfer the value of the data input to the output, whenever a positive pulse is received at the clock input jack.
The toggle flipflop is very useful for complex shape processing and combinations of key signals. The data flip flop is useful for quantization of input data, forcing the input to only update in time with the secondary clock signal.
PLEASE NOTE: This module requires connection to the Video Sync Generator by means of a Video Sync Distribution Chain Cable which must be purchased separately.
