phase filter

I had a rough weekend so my brain isn't working very well. So this question is probably pretty dumb.

Is there a passive circuit, like a filter, in which the output changes amplitude vs. a phase change of a CW signal at the input?

Thanks,

Yendori
 

Re: phase filter

No.

There ARE circuits that will take TWO inputs of differing phase and use that info to produce an output.
 

phase filter

All the amplifiers behave AM to PM conversion near saturation. This means that there are active circuits but I am not sure of passive.

Oh yes pre-distortion circuit is nothing but the AM to PM circuit.

You got the answer.
 

Re: phase filter

Ok got it. Thanks to both of you.
 

Re: phase filter

Did you both get points for helping me?

I know I am suppose to be a smart engineer, but I still don't understand how to thank someone for helping me so they get points.


I don't want to appear to be an ingrate.

Thanks
 

Re: phase filter

I wouldn't worry about it.

BTW, what is your application?
