SUMMARY

The discussion centers on the mathematical derivation of voltage values for on and off pixels in an N line matrix, specifically using the RMS waveform. The equations provided are V ^ 2 on = 1 / n ( V ^ 2 + 2vsvd + nvd2^2) and V ^ 2 off = 1 / n (V^2s - 2vsv + NVd^2). The optimal addressing condition is established as Vs / Vd = √N, leading to the maximum voltage ratio Von/Voff = (√N + 1) / (√N - 1). Participants emphasize the necessity of mathematical backing for conclusions drawn from these equations.

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?
