Signal Circuit of Duty Ratio Ajustable Clock Consisting of 4 NAND gates
As shown in graph, the circuit is composedof four NAND gates. Oscillation signal frequency is decided by C and the value of potentiometer RP1. RP2 . Changing the resistance of potentiometer can change the frequency whose adjustment range can be 20:1.The resistance of potentiometer RP2 sets the width of output waveform T1 ,and the resistance of potentiometer RP2 sets the width of the output waveform T2.
