Inverse of DC offset going down instead of up

Whats it called when a waveform starts BELOW the zero crossing point?

example: triangle waveform

starts from -6 goes up to +4

or starts -10 goes up to +2


Mostly DC offset Raises the Waveform up ABOVE the zero crossing point what makes the waveform go Below the zero crossing point? what would cause the circuit to do this?

Superimposed is taking a DC voltage and having AC waveforms riding on top
making the AC waveform go "Above the Zero crossing point

Is there anything else like a network or circuit that would make the AC waveform go 'Above" or "Below the zero crossing point?

Whats the inverse of superimposing?

DC offset in your cicuit is negetive.
if you use positive DC offset your wave increase as you say.
if DC offset = 0 then integral of your wave form for one period will be zerro. this means upper area with lower area of wave are equal.
in your example it will -5V, +5V.

how do i get Negative DC offset where the waveform starts at -12 or -10 , -6 what do i need to do ?

I dont know about detaild of your circuit.
Put your circuit schematic for evaluation.

Triangle waveform starting at -4 or -6 ,-8,-12 how do i do this?

Most common triangle or square waves start on the Zero reference point

examples most common

starts at 0 voltage and goes to +5 volts
so the triangle waveform or square wave
just goes from 0 to 5 volts

I'm not talking about this at all

How do i get Negative DC offset?
What circuit would make Negative DC offset?
Would i need a negative power supply to get Negative DC offset?

Triangle waveform starting at -4 or -6 ,-8,-12

example:

Triangle Waveform starts at -12volts and ramps up to +5 volts

how do i get the Triangle waveform or a Square waveform to start below
like starting with -12volts? or -8volts? or starting at -6volts?

The triangle waveform or square waveform is outputing negative voltages how do i do this?

I think you are talking about the swing: -6 to 4 volts or something like that.

I think that the swing is adjustable by the supply limits i.e if you have ±5 supply,
you could generate a ±(2,3,4....5)V sin, square, triangular wave.

The supply is the limit, you will never get a swing more than your supply.

just have a reference point (ground), and choose your suitable +ve and -ve supplies to match your required swing in your circuit.

Thanks for the information

Power supply is +12 to ground

if my reference is Zero voltage how do i start the Swing at -12 or -10 or -8
i want to start to the swing negative how do i do this?

If my op amps at +12 and ground and my transistors are +12 and ground how would my triangle or square waves get to start "Below" Zero voltage like -12 or
-10 or -8 and then it starts to swing but it starts on a Negative voltage and then swings from that point

With the clamper circuit it is possible.
see your schematic!
