Would any maths be needed for this?

[questions_uk]

Not sure if the question wants description and maths or one or the other. the question is:

A device responds to the RMS waveform given by:

V ^ 2 RMS 1 / T Integral T on the top and 0 on the bottom V ^ 2 (t) dt

Show that the on off pixels in an N line matrix get voltges given by

V ^ 2 on = 1 / n ( V ^ 2 + 2vsvd+ nvd2^2)

V ^2 off = 1 / n (V^2s - 2vsv+NVd^2)

show that the addressing is max'd when

Vs / Vd = sqre root of N

Giving the result

Von/voff max = square root of square root N + 1 / square root of n - 1

any tips appreciated.

thanks

You will have to show this mathematically. I don't see any part of the question that implies you will need to describe the relationships, but sometimes your solutions need to be backed up by a description so you can simply show what it is you just concluded from your solution.

Thank you for your reply. could you give some hints as to how to do this question?
