专利汇可以提供Compensation of attenuator专利检索,专利查询,专利分析的服务。并且PURPOSE: To prevent disturbance due to observation while facilitating automation by observing the rising edge characteric of an attenuator with a comparator itself to compensate for it.
CONSTITUTION: A pulse from a pulse generator 1 is propagated to a final end resistance R
0 with lines 2 and 3. The reference level Vref of a comparator 4 is set near the low level of the pulse and then, a strobe (b) to the applied to the point S is moved backward and forward detecting the output of the comparator 4 to detect the input pulse edge with a processor 5. Then, the Vref of the comparator 4 is changed by delaying the strobe pulse by a proper time from the edge detection position to determine the pulse high level. Then, the variable capacitor C
1 is adjusted to have the high level within the allowable range whereby compensation is done so that the relationship between resistances R
1 and R
2 and a compensation capacitor C
1 and the input capacitance C
2 of the comparator 4 meets R
1 C
1 =R
2 C
2 .
