I'm going to give a talk at a local radio club on Monday and want to
produce some handouts. The audience will be pretty non-technical, so
writing lots of equations with Greek symbols is not going to be on!
So I could resort to something like
S/N = s / (n1 + n2 + n3 +n4)
s = signal power
n1 = thermal noise
n2 = made made electrical noise
n3 = electrical noise from the Sun.
That would be better than Greek symbols, but I am still not sure it will
be understood too well.
So I was thinking of pictorially represent what they are.
s = signal power (perhaps draw a radio transmitter)
n1 = thermal noise (perhaps draw a coal fire)
n2 = made made electrical interference (perhaps draw a computer)
n3 = electrical noise from sun (perhaps draw the sun)
Is there a way of doing that in a notebook, such that that images (gif,
jpeg etc) could be used in equations and computations preformed on those
OK, you think I am mad! Perhaps I am, but I'm trying to get the idea of
using equations across to an audience where although a few might be
chartered engineers, the vast majority are frightened by Ohms law. They
*should* all have a clue what equations are, as they have all passed the
rather basic exam for an amateur radio license. But for anyone that know
s much about that (in the UK anyway), you would have to be pretty thick
to fail it.
If anyone has attempted this sort of thing, I'd be interested.
I think more often than not trying to teach something to someone whose
technical abilities are far below your own is more difficult than
teaching PhD students things.
