Hello Everyone!
I think my question would go here. Is there a method to find the period of a given periodic function? Say: where b is not necessarily an integer multiple of a
Thanks!
Is this anything to do with wiki: Beat (acoustics)?
2 cos (2丌f at) cos (2丌f bt) = cos (2丌f a -2丌f b)t + cos (2丌f a +2丌f b)t
f beat = f1 - f2
f beat = (f a +f b) - (f a - f b) = 2f b
period, T = 1/(2f b)? Is it?
