Analysis and Synthesis of Sequential Circuits using D Flip-Flops

INSTRUCTION

  1. Apply \(V_{CC1 }\) and \(V_{CC2}\), so that clock start button will be enabled. Apply low level voltage to ground(GND1) and (GND2).
  2. Next, start the clock pulse by clicking on the "Clock Start" button and after generation of some clock pulses stop the clock pulse by clicking on the"clock Stop" button .
  3. Now apply high voltage to D input and set "No of clock pulses" to 1. See the changes at output(Q and Q) at positive clock edge.
  4. Now apply low voltage to D input and start the clock pulse. See the changes at output(Q and Q) at positive clock edge.
  5. Note: Red symbolize as Low (L), Green symbolize as High(H).
