Introduction.

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