number of finite voltage levels
Yes. A signal of plateaus shows quantized or discrete levels of one or the other voltage; only 2 states. A sawtooth signal has a spectrum of states and has many more than 2 discrete states and is thereby analog. A sine wave is also an example of an analog signal - a spectrum of intensity.
We know that there are discrete levels energy levels because of the light that comes off of an excited atom.
Electrons occupied certain discrete energy levels around the nucleus.

an atom has electrons in discrete energy levels
The difference between max232 and rs232 is the voltage levels of the rs232 are high. In order to reduce those voltage means to convert those voltage levels to TTL logic levels we use max232 integrated chip which is a dual driver/ receiver.
The generation voltage of vtps is a variation of many different principles.
convert signal gains or losses to comparative decible reading.
