Device contains analog key, commutators of upper and lower levels, level shift circuits, generator of step voltage, OR element, impulses generator, RS-trigger, counter, AND elements of first and second groups, connected to output of device. Additionally introduced to device are mono-stable multi-vibrator and four generators, as a result of which number of counts is decreased time interval between which is less than time of relaxation of mono-stable multi-vibrator. |

Hardware-software device for multichannel conversion and recording of analog signals For each channel device has digital signal converter, block for setting conversion digitization frequency, conversion level adjustment block, block for transferring electric signals to physical values, block for observing converted signals, block of precision of signal conversion, block of signal conversion time, block for disabling unused channels, block for synchronization of analog signals, visualization block, converted signal recording block. Device allows to convert signals of different levels, to change digitization frequency and conversion time, to disable unused channels, transfer sensors signals to physical values with consideration of sensors scales, observe signals at different scales, appropriate to levels of converted signals, to measure precision of recording of converted signals. |
