Welcome to AAC. But we're going to need a whole lot more information before anyone can help.

 

Have no idea what you are trying to do.
Please tell us exactly, if you want help.

 

That first post could be a part number, or model number. Or a coded message request.
So note to "msowmya" These forums neither demand brevity nor reward it. In addition, there is no "per word" charge for posting requests for assistance.
Besides that, some of the more picky people, myself included, seek the whole context when a solution to a problem is requested. Of course, when adequate context is provided, very often a number of good to excellent solutions are usually provided.

 

What is mvx?

 

Do you want RMS, average, peak voltage and current?
What response time? How long to get to the answer?

Sinewave 450Kz

We could build a 4.5mhz sampling ADC and get a pretty good idea of what the wave looks like. Or use a 45mhz sampling rate and get more information. BUT I can also get a real good idea by sampling at 45.1khz. (under sample and take some time to get the waveform)
If the waveform is a good sing wave then we can do some tricks. But if the waveform changes to square wave we will not know it.
