Fig. 9 is the waveform of anti-jamming circuit embodiment, exports A3, Schmidt including touching pulse P1 and Schmidt circuit F11
Circuit F21 output A4, the waveform of control pulse M1.In Fig. 8, when touching pulse P1 and being maintained low level for a long time, A1 point is
Low level, the output A3 of Schmidt circuit F11 is low level；When touching pulse P1 and being maintained high level for a long time, A1 point is
High level, A3 is high level.When touching pulse P1 and becoming low level from high level, the output A1 of current driver U11 is immediately
Becoming low level current potential, A3 becomes low level from high level immediately.When touching pulse P1 and becoming high level from low level, A1 electricity
Position because current driver U11 output driving electric current to electric capacity C11 charging and rise, when charging between reach on T1, A1 current potential
When rising the upper limit threshold voltage meeting and exceeding Schmidt circuit F11, A3 becomes high level from low level；Positive pulse width as P1
Degree is less than T1, and when the charging interval is less than the upper limit threshold voltage of T1, A1 current potential not up to Schmidt circuit F11, P1 becomes low electricity

Galvanic electricity flows to electric capacity C21 charging and rises, when charging between reach T2, A2 current potential and rise and reach the upper limit of Schmidt circuit F21
During threshold voltage, A4 becomes low level from high level；When the negative pulse width of P1 is less than T2, A2 current potential less than T2, charging interval
When not rising the upper limit threshold voltage reaching Schmidt circuit F21, P1 i.e. becomes high level, and A2 is immediately turned into low level current potential,
A4 maintains high level state.In Fig. 9, the original state of P1 and A4 is low level.The rising edge of the positive pulse 11 of P1 makes A4 from low
Level becomes high level, and the width of the negative pulse 17 of P1 is more than T2, and after negative pulse 17 trailing edge 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, and the width of the negative pulse 18 of P1 is less than
T2, therefore, A4 is not affected by negative pulse 18, and A4 maintains low level state.Negative pulse 19, the width of negative pulse 20 are respectively less than
T2, A2 current potential cannot be charged to or be higher than the upper limit threshold voltage of Schmidt circuit F21, not affects A4 state；P1
The width of negative pulse 21 more than T2, therefore, after the trailing edge of the negative pulse 21 of P1 crosses time T2, A4 becomes low from high level
Level.At the rising edge of the positive pulse 16 of P1, A4 becomes high level from low level.
The output A3 of Schmidt circuit F11 touch pulse P1 be low level time keep low level, touch pulse P1 by
Low level is crossed time T1 after becoming high level and is just become high level.The output A4 of Schmidt circuit F21 is high touching pulse P1
Keep high level during level, after touch pulse P1 is become low level from high level, cross time T2 just become 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. 9, the original state of A3, A4 is low level, and the output Y of data selector T11 is low level, and data select
Device T11 selects A3 as exporting Y and being to maintain low level period at A3.When A3 becomes high level at edge 30 from low level
Time, output Y becomes high level, and data selector T11 selects A4 as output Y, and now A4 must be high level, maintains output Y
High level state.When A4 becomes low level at edge 31 from high level, output Y becomes low level, and data selector T11 selects
Select A3 as output Y, now A3 must be low level, maintain export Y low level state.When A3 becomes from low level at edge 32
During for high level, output Y becomes high level, and data selector T11 selects A4 as output Y, and now A4 must be high level, dimension
Hold the high level state of output Y.
