Chapter 18 Sequential Circuits: Flip-flops and Counters
wps.pearsoned.comDesign a counter with the following repeated binary sequence: 0, 4, 2, 1, 6. Use T flip-flops. Solution: Step 1: Since it is a 3-bit counter, the number of flip-flops required is three. Step 2: Let the type of flip-flops be RS flip-flops. Step 3: Let the three flip-flops be A, B and C. Step 4: The state table is as shown in Table 3.1.

The choice of flip-flop type can affect the complexity of the combinational logic in the resulting sequential circuit. Of three common types, the most versatile is the JK, since it can be easily converted into the other two.

Modeling Latches and Flip-flops - Xilinx
www.xilinx.comThe D flip-flop can be viewed as a memory cell or a delay line. The active edge in a flip-flop could be rising or falling. The following figure shows rising (also called positive) edge triggered D flip-flop and falling (negative edge) triggered D flip-flop. The positive edge triggered D flip-flop can be modeled using behavioral modeling as ...
Modeling Latches and Flip-flops - Xilinx
www.xilinx.comThe D flip-flop captures the value of the D-input at a definite portion of the clock cycle (such as the rising edge of the clock). That captured value becomes the Q output. At other times, the output Q does not change. The D flip-flop can be viewed as a memory cell or a delay line. The active edge in a flip-flop could be rising or falling.
ICL8038 - MIT
www.mit.eduthat the flip-flop is in a state such that current source #2 is off, and the capacitor is charged with a current I, the voltage across the capacitor rises linearly with time. When this voltage reaches the level of comparator #1 (set at 2/3 of the supply voltage), the flip-flop is triggered, changes states, and releases current source #2.

The outputs of the flip-flop drive an H-Bridge circuit that handles the high current going through the motor. If you were going to try to build a circuit to take a PWM signal and convert it to a motor position, you'd probably end up with a fairly large circuit.
