Drezno and Lipsk are the first in series of modules which constitute The Leibniz Binary Subsystem, a group of 8-bit signal processing devices offering comprehensive digital signal manipulation, as well as audio signal, control voltage, trigger, and gate generation. Drezno is the input/output front-end of the system, consisting of an analog–to–digital converter (ADC) and a digital–to–analog converter (DAC), that alone can be used for manipulating analog signals and voltages based on their binary representation. For detailed description, please refer to the manual.
