<p>Binary signals are decoded by a feedback circuit in the coder, to whose input binary signals are applied. Its output is connected to a first input of a comparator. Analogue signal is applied to its second input. The decoder is based on the feedback circuit in the coder. The coder feedback circuit has a function generator (V2, V3, C4, C5), which delivers a rising or falling output signal when the binary signal has its first or second binary value respectively. this signal is applied to the comparator (VGL) second input (2) with such polarity, that the difference between this voltage and input analogue is a minimum. The decoder has a function generator similar to that in the coder (V2, V3, C4, C5). Binary signals are applied to it, and the analogue signal is collected from its output.</p> |
