Why God exist
The existence of God has been questioned for several centuries
with different scholars putting forth different views. This
different opinion in God’s existence has lead to the emergence
of different religions. Some people belief that God exists while
others deny. This paper shows three reasons why I believe that
god exists.
First, the universe is so complex that even the scientists are still
researching on it. Its origin is still a mystery but as everything
else has a beginning then it too must have one. The heavenly
bodies co-exist with each pointing to an intelligent creator. The
complexity of our earth is also another pointer to the existence
of a creator. It is capable of sustaining all types of lives from
aquatic to terrestrials. This suggests that there is a supernatural
being that sustains and control the universe.
Secondly, one has to put into consideration the human body.
Different body parts are well coordinated resulting in smooth
operation. This points to the existence of an intelligent creator
as this kind of complexity cannot have developed due to
evolution as some scientist suggests. Each body part has its own
function just like the different parts of a motor vehicle have
been assigned different roles. The person responsible for this
creation is God as there is no human being capable of doing
this.
Thirdly, historians and archaeologists have been successful in
providing evidence to the existence of places mentioned in the
holy books. Cities mentioned in the holy books have been
located and excavated. What was found in these areas proves
that the holy books are accurate in their accounts of the
existence of a God. Historical scholars have been able to prove
some accounts in the holy books, for example the Pharaohs of

God does exist as He is the author of the holy book.

Assignment 1 – MP3 Player interface
This assignment is worth 15% of the unit assessment.
Due Date: Wednesday 23
rd
September 2015 at 10:30 am

3. 1. Submit a soft copy through https://esp.ict.swin.edu.au
-with cookies enabled and *.swin.edu.au added to your
trusted internet zone
2. Submit a report by hand at the 10:30 Thursday lecture.
Both components must be submitted on time.
Introduction:
This assignment requires a knowledge of logic gates, flip-flops,
counters, controlled gates and input / output.
Optional tasks require a knowledge of registers and
shift-registers.
The minimum assignment requirements:
Develop and submit an original logic circuit for the user
interface of a 5-button MP3
player. The interface must display the volume as an 8-LED bar
graph, the track number
and Play/Pause indicators (one LED for each).
The MP3 player interface must have the following controls and
displays:
1. A PLAY/PAUSE button.
2. VOL+ and VOL- buttons
3. <- (prev) and -> (next) buttons
4. An 8-LED bar graph indicating 8 volume settings
5. A 2-digit decimal display -two 7-segment displays (available
in the input/output
palette in CEDAR) to indicate the track number.
6. One LED which indicates PLAY mode (on) and PAUSE mode
(flashing 1Hz) OR
Two LEDs - one for each mode.
There is no requirement to implement the MP3 playing function,

4. the A-D convertor, audio
amplifier or other functions.
The MP3 player interface must have the following functionality
(minimum requirements):
1. Two states: PLAY and PAUSE.
2. In the PAUSED state, a single press on the PLAY/PAUSE
button should change
the state to PLAY, and the PLAY LED should be on. If a
separate PAUSE LED is
present it should be off.
3. In both PLAY and PAUSE states the VOL+ and VOL- buttons
should increase or
decrease the height of the Volume bar graph (8 LEDs). The bar
graph must not

wrap around if the VOL+ button is pressed while 8 LEDS are on
or if the VOL-
button is pressed and no LEDs are on.
4. In both PLAY and PAUSE states the -> and <- buttons
should increase or
decrease the track number display. The value must wrap around
when it teaches
99 or 00.

5. A screen-shot of your final circuit must be included in a report
which you will submit both
electronically (through ESP) and on paper. Details of the report
are shown below.
Parts 1-4 constitute 40% of this assignment and are compulsory.
For additional credit:
5. Three states: Off, On (PAUSED), ON(PLAY). When in the
OFF state all LEDs must
be off and all buttons must not respond, except for the
PLAY/PAUSE button which
should only respond when held down for 5 seconds.
6. When entering the ON state, the player should start in the
PAUSED state. The Play
LED should be off (if a separate PAUSE LED is present) or
flashing.
7. When in the PLAY/PAUSE mode if the PLAY/PAUSE button
is held down for 5
seconds, the MP3 player should change to the OFF state, with
all LEDs off. The
values in the Volume and Track number displays do not have to
be stored.
Parts 5-7 constitute 30% of this assignment and must be
attempted.
For a distinction grade or better:
8. When entering the OFF state the values of the volume and

6. Track number displays
must be stored in appropriate registers.
9. When entering the PLAY/PAUSE states (from the OFF state)
the values in the
Volume and Track Number resisters must be loaded into the
appropriate displays
and counters.
10. Implement a fast forward (FF) state to be entered when the
user holds down the ->
button for 5 seconds. This will cause the PLAY LED to flash
quickly (~4Hz). To exit
this state hold down the <- button for 5 seconds to resume
PLAY mode.
Parts 1-4 must be completed successfully to qualify for a pass in
COS10004.
Parts 5-7 constitute 30% of this assignment, and must be
attempted.
Parts 8-10 are optional.
Marking details:
• Each requirement is worth 10% of this assignment or 1.5% of
this unit.
• In order to get 100% (15% of the unit result) you must
complete all 10
requirements.
• To "pass" the assignment you must complete requirements 1-4
and attempt parts

7. 5-7 (50%).
• To qualify for a pass in the final unit result, you must get at
least 35% of this
assignment (requirements 1-4). 35-49% is a fail for the
assignment, but will not
disqualify you from passing the unit.
• If you do not complete requirements 1-4 (at least 35%) you
will receive a final mark
no higher than 44% for this unit.
• Circuits will be examined using CEDAR. While you may
develop in other
simulators, your final submission must be a CEDAR file.

Hints:
• Start with a toggle circuit to switch between PLAY and
PAUSE states. Include indicator
LEDs and a low-frequency timer for the PAUSE indication
(optional).
• Construct a decimal counter connected to VOL+ and VOL=
buttons. Add logic circuitry to
disable the appropriate button when the limits are reach (to
prevent wrap-around).

8. • Next, build a binary counter which counts from 0 to 15 (up
and down). Add logic circuitry
to wrap around from 9 to 0 (with Carry out). Connect Co to the
input of a second 0-9
counter. Connect to two 7-segment displays and test. Make sure
that when counting
backwards the counter goes from 0 to 99.
• Create a 5-state countdown counter (4,3,2,1,0) and a 0 detect
gate. Add gates to the PR
pins of the flip-flops to reset the FFs to 5 (101) when not in use.
• Use an OR gate to detect if PLAY or PAUSE states are active
and use this to enable or
disable other buttons and displays. Do not use it to disable the
clock – you need that to
keep running.
• When the user presses PLAY/PAUSE start the countdown
timer. If the user releases the
button before the counter gets to zero, change state (from PLAY
to PAUSE etc.)(if not
OFF) and reset the timer. If the timer reaches 0, change state to
OFF (or ON) and reset the
timer.
• THIS ASSIGNMENT IS HARD – START NOW

Design outline:
My design uses 5 ½ bit adders, 23 registers, half a right-shift
register, and a binary counter, blah blah, blah. If you try to
construct this circuit, it will never work because this doesn't
make sense. Try reading the notes, doing the labs and
experimenting with CEDAR. Blah blah blah.

Unresolved Problems:
My circuit cannot fly no matter how hard I try. Maybe
increasing the clock frequency into the MHz (micro seconds)
range will help, but CEDAR does not support this. [Glcr n
