I currently assigned to do a oral presentation about enginnering process..

It is required to present a engineering process of a electronic devices..
for example a digicam..
I need to explain from the raw material of making a digicam to the end product..
it is not neccessary to explain how the internal components work..
it jus have to explain the production process..

have anyone here got any idea? or relavent website?

i am measuring the frequency of servo motor which coming out as 3 phase ac signal. i am measuring the frquencu between two phases, on the frquency meter. if i measure it on meter it is showing correctly, but as soon as i connect cro (scope) to it, is getting disturbed and showing any random value. why it so?
