Figure: Five-divider frequency circuitWhen the counting pulse is input from the INB, the output would be QB, QC and QD. Such would form quinary counter (also called five-divider frequency circuit), whose circuit is just as shown in Figure 2-3. Use four-trace oscilloscope to record the output waveform. (View)

Figure: Symmetric multivibrator circuitMultivibrator is a self-oscillation circuit. Because there is no stable working state, multivibrator is also known as non-steady-state circuit. Specifically, if the multivibrator is at the state 0 at the very beginning, it would keep the state 0 for a period of time and then automatically run into state 1afterwards. If it remains state 1 for a period of time, it will automatically transfer to state 0. Such transfer would occur again and again, outputting the rectangular wave. (View)

Published:2011/6/5 10:52:00 Author:John | Keyword: prolonging signal light
Use former two out of 4011 CMOS’s 4 non-door to constitute a chopper oscillator. And use a 1MΩ potentiometer to change the duty cycle. If the third non-door is not connected, it is helpful to apply the input end of the fourth non-door into the integrated circuit (14). Before the power is turned, the potentiometer is firstly transferred to the middle position and then is regulated. In order to prolong the original battery life of 3 times, 50% duty cycle should be provided signal light with intermittent signal current and double voltage.
