I am thinking of some basic question about LO and I cant figure it out

I need your help to give me some explanation so I can further investigate my text book.

Say there are 3 signals [frequency at wo-k, wo, wo+k]going into the input of a LO. Then due to the nonlinearity of LO, we get Intermodulation harmonics terms. If wo is the desired frequency while the other two are interferers, my question is at which frequency Local Oscillator will tune at?

For any theoritical and practical purposes, what is the method to find the oscillator frequency and/or period?

Maybe this question sounds too general. Therefore, if you have any further details to complement this question and doubts, kindly share your views.

Thank you

rgds and thanks
