Clock, duty ratio were 12% (initial duty cycle+first time 10%), and when increasing for the second time, the time continues 1 point 10 seconds, duty ratio
For 32% (it is 20% that second of initial duty cycle+first time 10%+, which increases ratio), the third time increase time continues 1 point 30
Second, duty ratio is that 62% (second of increase ratio of initial duty cycle+first time 10%+ is that 20%+ third time increase ratio is
30%), and so on.Similar, increase the duty ratio of the ratio of successively decreasing of pwm signal according to incremental time interval.Alternatively, can
To be interpreted as increasing according to the time interval successively decreased the duty ratio of the increasing proportion of pwm signal, for example, when increasing for the first time, when
Between continue 1 minute, duty ratio 12%, second when increasing, and the time continues 40 seconds, duty ratio 32%, when third time increases
Between for 20 seconds, duty ratio 62%, and so on；Similar, increase the decline ratio of pwm signal according to the time interval successively decreased
The duty ratio of example.
