A counter-top uses flip-flops to " remember” the past
count before the clock heartbeat occurs.
A shift signup can shop several incidents in series
depending on the length of the register.
A shift register such as a Johnson counter, can be
set which has a characteristic collection like a countertop
and can be found in applications demanding a
This research requires two count sequences.
Either may be completed initially. The one finished
first must clear equally clear both counters.
The counters happen to be " clocked” manually by
The logic function of the routine can be designed
by using a basic D flip flop countertop.
The logic function might also be created by:
1 . Creating a state diagram of binary counts
2 . Using a transition table, populate present and
up coming state desks
The lab calls for a 74175 IC nick to be applied as the
counting gadget. Since we will be counting two
separate is important, one for strikes and one intended for balls,
TWO 74175 IC chips to be used.
Work in improvement
We had to use 4 of the 7474 rather than the 74125
The CLR triggers when ever either Q2 OR Q7 the CLK is
connected to the Pushbutton routine. D0 is connected to
+5V. D1 is usually connected to Q0. D2 is connected to Q1. For the
Balls table; D4 is usually connected to +5V. D5 is connected to
Q4. D6 is usually connected to Q5. D7 is connected to Q6
The 74175 IC nick contains 4 D flip flops. Knowing this kind of we
can easily feed the output of the initially into the suggestions of the following
forming a counter. Making use of a positive voltage +5V upon D1
and connecting the CLK to a +5V if the STRIKE BUTTON
is pushed to cycle the counter-top. The airport terminal count is 2 for strikes and 3 intended for balls. Therefore the output of the third M flip lemon will be connected to the clear capabilities of all connected
counting flip flops.
