Workshop PG5 Exercise Chapter 4<br />
The function of the RS dynamized Flip-Flop is that of a latch. When there is a<br />
signal going from low to high on the R input, the latch is said to be reset, and the<br />
output Q will be low, and stay in this state, until a signal going from low to high<br />
on the S input occurs, and then the latch is said to be set, and the output Q will<br />
be high. If both receive a low to high signal at the same time, the output will be<br />
low.<br />
Erase all the connections to both the right and left column. You will have just two<br />
AND gates on the page. Change the AND gate that has 4 inputs from 4 to 2.<br />
(you will have to erase it and put a new one on the page) Remove any binary<br />
inverter symbols from the inputs of the AND gates. Paste the RS Flip-Flop between<br />
the AND gates and the right column. Connect Input0 and Input1 to the<br />
top AND gate and Input2 and Input3 to the bottom AND gate. Connect the<br />
output of the top AND gate to the R input of the Flip-Flop and the output of the<br />
bottom AND gate to the S input of the Flip-Flop. Connect the Q output of the<br />
Flip-Flop to the Output0 of the right column. Delete Output1 from the right column.<br />
Your program should look similar to the drawing below.<br />
Build and download the program. Go online and activate the run mode.<br />
When Input0 and Input1 go high, this will reset the flip-flop and Q will be low.<br />
Turn on Input2 and Input3, and Q will be high. Led 32 should be on. Turn Input0<br />
and Input1 on again, and Q will go low. Set and reset the Flip-Flop several times<br />
to see the operation. Remember this is a dynamized Flip-Flop, so it operates on<br />
the rising edge of the signals. There are a few different versions of this Flip-Flop<br />
available.<br />
