1989 Binary Conversion Komputor
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 convert- er (DAC), that alone can be used for manipulating analog signals and voltages based on their binary representation (see: ‘Binary Code’ paragraph).
Lipsk (sold separately) is a binary logic processing expander module that can flip (invert) individual bits of the digital signal representation.
Drezno consists of a flexible ADC (analog-to-digital converter) and DAC (digital-to-analog converter) that can be cross-patched, or used independently. It offers:
- digital manipulation of analog signals and voltages
- converting slowly changing voltages to 8 rhytmic gates
- converting combinations of up to 8 gate signals to complex waveforms
- quantization and bit mangling or crushing of signals
- a digital sample&hold function
The input is converted to digital representation and made available in the form of 8 binary (gate) signals. These signals can be freely mixed, scrambled, inverted, cross-patched, etc. At the end, 8 binary signals are converted back to analog domain. Both conversions may be performed synchronously with external clock patched to respective clock inputs, or asynchronously, at high speed of internal clock.
Drezno can handle signal changes as fast as 1MHz, so there is no aliasing with audio rate input.
Drezno may also act as an input/output device for an upcoming barebone digital signal processing subsystem.
