Err.... I'll likely be showing my ignorance here....

The way I understood it, in Class C the transistor is conducting over a
narrow conduction angle, but it is reatively linear during that section.

It conducts in a short "Raised Cosine" burst...  that is, a Class C
transistor is not hard limiting.

If it were being switched hard on and off it would be in Class "D" or
perhaps Class "E"......
