Flowchart
If you where making a steady hand game then your flow
chart would look something like the below
A
systems approach to designing a circuit
When we design large complicated circuits it really helps us
if we devise a way of chopping then up so they can be worked on one section at
a time. To do this we need a system for how we chop them up.
So … we look at the inputs and the outputs separately (nearly
all circuits have inputs and outputs) and everything else must be a process,
meaning the things that happen between the inputs and the outputs.
Inside the process there may be many different systems (we
call them sub systems). For example if you made the steady hand game there is two main processes, the timer and the counter. If you
made an alarm system that goes off for a set amount of time then the processes
would be the timer and the pulse generator (a stable or oscillator).
You need to create a diagram for your circuit which explains
what your system consists of..
Here is a system for the steady hand game shown above
Notice how on each level
down, we become more specific about what we are going to use within our own
circuit..
You now need to create one of these diagrams
for your own circuit
