A Design Classic Transistor Flip-Flop Circuit Simulation
A lot of people interested in electronics applied a variation of the classic two-transistor flip flop circuit design using 2 different operating states provided the same circuit. LEDs are enabled 6.
first transistor T1 now suppose that the message (D4 -D3 BURN OFF ) . In this case T1 collector voltage will be closer to zero volts, and for the first time would be short-circuited capacitor C1 to bias the base of transistor T2 and T2 will fall will enter into insulation . Capacitor C1 through resistor R3 is the base bias of transistor T2 times of charging will increase relatively .
