Bob –

Sorry, but I have no idea of what you are claiming. The mathematical process of multiplication is always linear. 73 – Mike

Hi

If you accept the definition that a “linear” circuit *only* produces the input times some constant ( = the gain ) then anything that multiplies must be non-linear.

If you look at a different definition, then of course, they can be linear.

It’s just a mater of what your base definitions are.
