A1 points are low level, and the output A3 of Schmidt circuit F11 is low level；When input pulse P1 is maintained high level for a long time,
A1 points are high level, and A3 is high level.When input pulse P1 becomes low level from high level, the output of current driver U11
A1 is immediately turned into low level current potential, and A3 becomes low level from high level immediately.When input pulse P1 becomes high level from low level
When, A1 current potentials rise when the driving current that current driver U11 is exported charges to capacitance C11, when charging between reach T1, A1
When current potential rising meets and exceeds the upper limit threshold voltage of Schmidt circuit F11, A3 becomes high level from low level；When P1 just
Pulse width is less than T1, and the charging time is less than T1, and P1 becomes when A1 current potentials are not up to the upper limit threshold voltage of Schmidt circuit F11
Into low level, A1 current potentials are immediately turned into low level current potential, and A3 maintains low level state.In Fig. 3, the original state of P1 and A3 are low
Level.Positive burst pulse 11, positive burst pulse 12, positive burst pulse 13 width be respectively less than T1, A1 current potentials can not be charged to or surpass
The upper limit threshold voltage of Schmidt circuit F11 is crossed, A3 states are not influenced；The width of the positive pulse 14 of P1 is more than T1, therefore,
After the rising edge of the positive pulse 14 of P1 crosses time T1, A3 becomes high level from low level.The failing edge of the positive pulse 14 of P1 makes
A3 becomes low level from high level, and the width of the positive pulse 15 of P1 is more than T1, after 15 rising edge of positive pulse crosses time T1, A3 from

Level becomes high level, and the width of the negative pulse 20 of P1 is more than T2, and after 20 failing edge of negative pulse crosses time T2, A4 is from high level
Become low level.The rising edge of the positive pulse 12 of P1 makes A4 become high level from low level, the negative pulse 20 of P1, negative pulse 21
Width is respectively less than T2, and therefore, negative pulse 20, negative pulse 21 do not influence A4, and A4 maintains low level state.Negative pulse 23 is born
Pulse 24, negative pulse 25, negative pulse 26 width be respectively less than T2, A2 current potentials can not be charged to or higher than Schmidt circuit
The upper limit threshold voltage of F21, does not influence A4 states；The width of the negative pulse 27 of P1 is more than T2, therefore, in the negative pulse of P1
After 27 failing edge crosses time T2, A4 becomes low level from high level.In the rising edge of the negative pulse 27 of P1, A4 becomes from low level
For high level.
The output A3 of Schmidt circuit F11 input pulse P1 be low level when keep low level, input pulse P1 by
Time T1 excessively just becomes high level after low level becomes high level.The output A4 of Schmidt circuit F21 is height in input pulse P1
High level is kept during level, time T2 is crossed after input pulse P1 becomes low level from high level and just becomes low level.In other words,
When A3 is high level, A4 must be high level；When A4 is low level, A3 must be low level.
In Fig. 3, the original state of A3, A4 are low level, and the output Y of data selector T11 is low level, and data select
Device T11 selects A3 as output Y and is maintained in A3 for low level period.When A3 becomes high level at edge 30 from low level
When, output Y becomes high level, and data selector T11 selects A4, and as output Y, A4 must be high level at this time, maintain output Y
High level state.When A4 becomes low level at edge 31 from high level, output Y becomes low level, data selector T11 choosings
A3 is selected as output Y, A3 must be low level at this time, maintain the low level state of output Y.When A3 becomes at edge 32 from low level
During for high level, output Y becomes high level, and data selector T11 selects A4, and as output Y, A4 must be high level at this time, tie up
Hold the high level state of output Y.
