<p>In case when only one compensation of phase erros is to be carried out, phases of output voltages of all channels except one are split, so that they differ by 90 deg., and the two voltages of each pair are separately multiplied by the channel output voltage which has not been converted. They are passed through a filter and a latching circuit, multiplied by themselves and added in pairs to form a sum voltage. If in addition amplitude errors are to be compensated, either both voltages of each pair, or their sum voltage are in addition divided by the square of one or both voltages of the same pair, and passed through a filter and latching circuit. Or each of the two voltages in a pair is squared, passed through a filter and latching circuit and multiplied by both voltages of each other pair, or by their sum, and by the non-converted channel output voltage.</p> |
