In order to calculate the duty cycle, we need to first find the frequency or period of the variable signal. This can be found with multiple methods, but the initial approach can be to measure the pulse width of the transmitted signal. To do this with an unknown signal, we can connect t...

a对该信号进行连续两次二分频(由D触发器加反相器构成)即可得到脉宽为1s的计数使能信号Cnt_En Carries on the continual two two frequency divisions to this signal (to add phase reverser constitution by the D trigger) then to obtain the pulse width is the 1s counting enables signal Cnt_En[translate]...
Over this length of time the laser frequency needs to be actively stabilised in order to prevent the carrier frequency of the pulse from drifting. We use a technique similar to that described in Ref. [9]. The experimental parameters required to give suitable frequency references were found ...
