Abstract:
A device for converting an input signal of various formats to NRZ format in a user-selectable format with automatic self-testing, comprisinga) at least one first channel, where each at least one first channel has a first input, a second input, a first control input, a second control input, a first output, and a second output;b) at least one second channel, where each at least one second channel has an input, a control input, a first output, a second output, and a third output;c) at least one third channel, where each at least one third channel has an input, a control input, a first output, a second output, and a third output;d) at least one fourth channel, where each at least one fourth channel has an input, a control input, a first output, at least one second output, at least one third output, and at least one fourth output;e) a controller, having a control output, a first output bus, and a second output bus;f) a multiplexer, having an input bus, a control input connected to the control output of the controller, and an output bus connected to first input and second input of the first channel, the input of the second channel, the input of the third channel, and the input of the fourth channel;g) a demultiplexer, having an input bus connected to the second output of the first channel, the second output and the third output of the second channel, the second output and the third output of the third channel, and the at least one second output and the at least one third output of the fourth channel, having a control input connected to the control output of the controller, and having an output bus;h) a comparator array, having a first input bus connected to the output bus of the controller, having a second input bus connected to the output bus of the demultiplexer, and having an output array; andi) having a lamp array connected to each first output of the at least one first channel, each first output of the at least one second channel, each first output of the at least one third channel, each first output of the at least one fourth channel, and the output array of the comparator array.
