So I'm studying for a Signals and Systems exam and I can't seem to remember the simplest of trig problems.
How do you calculate the period of two sinusoids mutliplied together?
ie
sin(2 pi f t) .* cos (2 pi f t)
f being the frequency
t being the varible (time)
pi is that 3.14 thing
I know that with addition it's the LCM of the periods, but I don't know about products.
