Peter

Have a nice day. I think there is little more that can be accomplished
continuing this banter. You can believe what you wish.

+++ The amplitude does not.
+++

+++Of course not, *you* are using an absolute value.
+++
+++The waveform is the relationship between changes in amplitude

+++
+++The amplitude should have a maximum value of 1...

+++ The maximum voltage of a sine is 1, thus Vm is the

+++Diagrams in the book show exactly that. But, as you may

+++So, as said before...

+++ Amplification This essential process involves an increase
